Harish - Expert: Hi, I m hosting the Chat for today !!!

Harish - Expert: Welcome and I am waiting for your questions

hariraj: anyone there?

Harish - Expert: Hi Hari

Harish - Expert: Tell me

hariraj: hi harish

Harish - Expert: Today I am hosting this expert chat on ASP.NET 2.0 Caching and Security Features

Harish - Expert: feel free to ask your questions

hariraj: oh gr8

hariraj:

Harish - Expert:

hariraj: what will the format of data stored in cache

hariraj: will it be stored as xml?

hariraj: or as encrypted text

Harish - Expert: it is stored as encrypted

Harish - Expert: it is actually stored in the memory

hariraj: in clent or in server?

Harish - Expert: in 2.0, you have the facility to write to the disk

Harish - Expert: server

hariraj: can't i store it in client

hariraj: we have an attribute called location="clent/server"

hariraj: any idea about it

Harish - Expert: for storing it in client, you have to either use XML island

hariraj: whatz the purpose the location attribute then

dotnetjunk: How to secure config files

Anbirkiniyan: How to invalidate caching

Harish - Expert: location attribute is to set whether the cache is going to be downstream

Harish - Expert: sensitive etc.,

Harish - Expert: caching can be invalidated in different ways

Harish - Expert: in ASP.NET 2.0, you can use SQL Server notification

hariraj: whatz that downstream senstitive

hariraj: ya that i know

Harish - Expert: if it is Yukon SQL Server 2005, you can use poling

Harish - Expert: which is automatically enabled to find whether the cache data is invalid

hariraj: r u talking about connection pooling

Anbirkiniyan: How to do in .NET 1.1

hariraj: or is there any new pooling concept 2k5

Anbirkiniyan: What's the best practices in the Output Cache directive

Anbirkiniyan: How it's valid in .NET 2.0

Anbirkiniyan: Any new features in .Net 2.0 in caching

rambabu: hi friends

Harish - Expert: yeah it is there

hariraj: what are the new features added in asp.net 2.0 caching for Microsoft content

management system

Harish - Expert: its poling

hariraj: okie

Harish - Expert: poling is the mechanism by which your application keeps poling the sql server database to find whether the data has changed

Harish - Expert: priori to 2.0 version, for enabling data caching, you have to manually insert data into cache and retrieve it

hariraj: is't so?

Harish - Expert: u still need to do some plumbing work if you are using SQL server 2000 or earlier versions in combination with .NET 2.0

Harish - Expert: yeah

Harish - Expert: hi rambabu

hariraj: are u talking about data caching

Harish - Expert: yeah absolutely

Harish - Expert: Caching based on Database changes

hariraj: ok

Harish - Expert: for setting the dependency on files, you already have methods built in

hariraj: so how u ignore manual update in asp.net 2.0

Harish - Expert: you dont need to ignore.

Harish - Expert: if you still wish you can do that

hariraj: ok i want to ignore

Harish - Expert: these are new features in 2.0 that enable easier way of implementing Robust Scalable appliactions

Harish - Expert: just set the diskoutput attribute to false

hariraj: in?

Harish - Expert: in the page directive

hariraj: where should i've specify diskoutput attribute

Harish - Expert: <%@ OutputCache Duration="3600" VaryByParam="none" DiskCacheable="false" %>

Harish - Expert: to disable storing the cache in the disk

hariraj:

rambabu: hi Harish How to use cache

hariraj: this is page level caching

hariraj: am i rite

Harish - Expert: correct

Harish - Expert: if you disable page level caching

Harish - Expert: you can set your own datacaching mechanisms by writing in code

hariraj: but u said something about manual update

hariraj: whatz that?

Harish - Expert: either as inline or codebehind

rambabu: Harish we want application level cache How am i work

Harish - Expert: manual update is what i referred to setting the data into cache using codebehind

Harish - Expert: Cache.Insert

hariraj: is this not possible in 1.1

Harish - Expert: i m telling the same thing

Harish - Expert: it was possible in 1.1

hariraj: oh ok

Harish - Expert: polling based cache was not possible in 1.1

rambabu: at application level we want

hariraj: what are the new features added in asp.net 2.0 caching for Microsoft content

management system?

Harish - Expert: i have to check about that

Harish - Expert: CMS is not a part of today's topic

Harish - Expert: check http://harishmvp.blogspot.com for more information on the new caching techniques

Harish - Expert: well that doesnt stop you from asking questions here

hariraj: my question was related to caching

hariraj: ok anyway leave it

Anbirkiniyan: What are the best practices in CACHING

Anbirkiniyan: What to Cache and what not to?

Harish - Expert: you can cache data that is redunant

Harish - Expert: or non-sensitive

Dhrumit: Fist of all can you list out the techniques for caching which are new in ASP.NET 2.0 ?

hariraj: what is the purpose of sqldependency attribute?

Harish - Expert: say you are building a page where there is data that doesnt change frequently, you can implement caching

Harish - Expert: you can split up your page based on static and non-static sections and apply caching accordingly

hariraj: this is not new in 2.0

Harish - Expert: if you are stowin some information like Stock Rates etc., then its bad to go for caching

Harish - Expert: this is the answer fo the person who asked what to cache and what no to

Harish - Expert: new techniques in 2.0

Harish - Expert: 1. SQL Cache Notification 2. Using the Disk Output Cache 3. Post-cache Substitution 4. SQL Cache Invalidation 5. Cache Configuration

Anbirkiniyan: Best practices?

hariraj: that guy is sitting next to me

hariraj: hahahaha

Harish - Expert: oh thats fine i cannot make out from here

Harish - Expert: in addition you have the substitution control

Harish - Expert: Best practices

Harish - Expert: Dont set small expiration time

Harish - Expert: setting smaller duration doesnt improve performance of your application

Dhrumit: Now can we go one by one on these techniques ?

Harish - Expert: sure

hariraj: i've got an cricket application which has to fetch the content from my partner xml

Harish - Expert: ok?

hariraj: i've to update my site frequently ball by ball

hariraj: on that case i can't set a longer duration na

Harish - Expert: then dont cache the portion where scores appear

Harish - Expert: dont use caching at all for that situation

Harish - Expert: i told, if you show sensittive data, you cannot cache

Harish - Expert: sensitivity is time-sensitive

hariraj: but i want to use cache

Harish - Expert: if you show a 5 ball old score by implementing caching, then you are on for a toss

Harish - Expert: you cannot use

hariraj: because there are chances where my partner url go for a toss

hariraj: on that case i don't want show my users an error page

Harish - Expert: caching is meant for rendering rather static or semi-static info

Harish - Expert: what is that

hariraj: so i prefer to go for cache

Harish - Expert: thats a skeptical situation

Harish - Expert: so, in that case, you need to store your cache in the form of XML down the browser

Harish - Expert: and display in case error happens

hariraj: thatz that i've done

hariraj: thatz wat i'v done

Harish - Expert: Good

hariraj: but even on that case i've to refresh my content cached content frequently na

rambabu:

hi

Harish - Expert: that really doesnt improve the performance

Harish - Expert: hi

Harish - Expert: it rather looks like caching is being used for the sake of using

hariraj: brrrrr

Harish - Expert: you need to decide this at the architecture level

rambabu:

bera

Harish - Expert: comign to dhrumit

Harish - Expert: are you there dhrumit

Bijoy: How can one store XML in browser as cache

hariraj: we won't test our live application just like that

Dhrumit: Yes

Harish - Expert: ok SQL dependency notification is the new mechanism

Harish - Expert: by which you can set a dependcy for your tables

Harish - Expert: and when data is changed in the table, you can invalidate the cahce

Harish - Expert: say you are showing a table data is a Grid on your page

Harish - Expert: if you want your cache to get automatically invalidated when the table data changes

hariraj: what is the use of aspnet_regsqlcache utiltity?

Harish - Expert: you can implement it easily

Harish - Expert: i m coming to that

Dhrumit: Thats a nice feature. Where to implement it on page or at backend?

Harish - Expert: at the page level you have to set

Harish - Expert: aspnet_regsql.exe - is to enable poling for your SQL Server 2000 or earlier version of databases

Harish - Expert: Yukon and Whidbey are tightly integrated and they have more of interoperability within each other

Harish - Expert: hence you dont need to use the aspnet_regsql.exe - explicitly if you are targetting a Yukon database

hariraj: tell me this harish. Is Pooling different from poling

Harish - Expert: poling is the mechanism by which you keep pinging to some destination

Harish - Expert: pooling is the mechanism by which you retain a open resource such as connection such that it is available for subseauent requests

Dhrumit: I think we are running out of time. Lets first complete the main topics from expert. Then at the end we can have Q / A.

Harish - Expert: To set caching at the page level,

Harish - Expert: <%@ OutputCache Duration="999999" SqlDependency="Pubs:Authors" VaryByParam="none" %>

Harish - Expert: well this attribute sets the dependency on the table Authors in Pubs databae

Harish - Expert: if you are having SQL Server 2000

Harish - Expert: you need to register using the aspnet_regsql.exe -S ".\SQLExpress" E -d "pubs" -ed

Dhrumit: This will work only for data in grid or any other control too?

Harish - Expert: it will work for Page or any Datasource

Harish - Expert: you can set the cacheability to a datasource as follows:-

Harish - Expert: <aspqlDataSource EnableCaching="true" CacheDuration="Infinite" SqlCacheDependency="PubsDB:Authors" ... />

Harish - Expert: sorry

Harish - Expert: <asp: SqlDataSource EnableCaching="true" CacheDuration="Infinite" SqlCacheDependency="PubsDB:Authors" ... />

Harish - Expert: so once you specify this Datasource to your Control, that gets the functionality

Harish - Expert: i gave the aspnet_regsql command to register the database for poing

Harish - Expert: then the Table needs to be registerd for poling

Harish - Expert: aspnet_regsql.exe -S ".\SQLExpress" -E -d "pubs" -et -t "authors"

Harish - Expert: this command registeres the Authors table

Harish - Expert: the next hing you need to do is set the property in web.config

Harish - Expert: <caching> <sqlCacheDependency enabled="true" pollTime="1000" > <databases> <add name="PubsDB" connectionStringName="Pubs" /> </databases> </sqlCacheDependency> </caching>

Dhrumit: Ok means in case of SQL server 2000 we have to run this command. And in YUKON we

dont need to do it, right?

Harish - Expert: Absolutely right

Harish - Expert: i m trying to convey this special news

Harish - Expert: Yukon and Whidbey are termed to as Romeo : Juliet

Dhrumit:

Harish - Expert: they sync up with each other very well

Harish - Expert: The other big advantage is that, off topic you can run your C# functions as

extended procedures from Yukon

Harish - Expert: anyway, thats a different topic

Dhrumit: ya i know that. Thats right. And I heard they this romeo-juliet going to marry on 7th

November

Harish - Expert: so, next thing to do is after running the command for registering the database, table and web.config just specify the output cache parameter either for the page level or datasource as explained above

Harish - Expert: thats news for me

Harish - Expert: who is romeo & who is juliet

Dhrumit: I mean to say VS 2005 release date is 7th Nov.

Harish - Expert: thats skeptical

Dhrumit: What exactly to specify in Web.Config.

Dhrumit: ?

Harish - Expert: VS 2005 might get delayed a little bit

Dhrumit: Ok. Let get back to main topic.

Harish - Expert: sure

Harish - Expert: <caching> <sqlCacheDependency enabled="true" pollTime="1000" > <databases> <add name="PubsDB" connectionStringName="Pubs" /> </databases> </sqlCacheDependency> </caching>

Harish - Expert: let me explain each of the attributes

Harish - Expert: in web.config within the system.web tag

Harish - Expert: you put the sqlcachedependecy

Harish - Expert: set enable true

Harish - Expert: polltime specifies the interval at which the database will be contacted

Harish - Expert: the Databases is where you add all the DAtabases for which you need to

enable polling

Harish - Expert: these are the things you specify in the web.config

Dhrumit: ok

Harish - Expert: again reminding you, it is only sql server 2000 or earlier

Bijoy: I heared a GUI is available for each virtual directory, so it's easy to do right

Harish - Expert: is it a 3rd party?

Harish - Expert: can i move to next topic

Chatanya: Wats changes In Yukon

Harish - Expert: hi chatanya

Chatanya: hi harish

Harish - Expert: we are discussing abut the new caching features in yukon

Dhrumit: Bijoy, u r right. There ll be a web based interface for Web.Config. Harish we can move on next topic.

Harish - Expert: Sql Server 2005 Notification-based Cache Invalidation

Harish - Expert: so i explained about how to enable cache for sql server 2000

Harish - Expert: its even simpler for 2005

Harish - Expert: in the page directive set <%@ OutputCache Duration="999999" SqlDependency="CommandNotification" VaryByParam="none" %>

Harish - Expert: if it is for a DataSource

Harish - Expert: <aspqlDataSource EnableCaching="true" SqlCacheDependency="CommandNotification" CacheDuration="Infinite" ... />

Harish - Expert: again sorry

Harish - Expert: <asp: SqlDataSource EnableCaching="true" SqlCacheDependency="CommandNotification" CacheDuration="Infinite" ... />

Harish - Expert: thats all you need to do

Harish - Expert: Whenever a command is issued to Sql Server 2005, ASP.NET and ADO.NET will automatically create a cache dependency that listens to change notifications sent from the Sql Server.

Harish - Expert: As data is changed in Sql Server, these notifications will cause the cached queries to be invalidated on the web server.

Harish - Expert: The next time a page or datasource control associated with the dependency is requested, the page or datasource control will be executed again as opposed to serving cached information.

Harish - Expert: Guys, i have ejust explained 2 of the mechanims

Harish - Expert: Can we move to others?

Harish - Expert: I guess we are running out of time

Harish - Expert: so i will take all questins at the end of session?

Dhrumit: ya right

Harish - Expert: Disk Output Cache

Harish - Expert: we will talk about that now

Harish - Expert: You may/may not be aware that Cache is memory senstitive

Harish - Expert: once the isolation is reached, cache cannot be withheld

Harish - Expert: similarly cache cannot stand application restarts

abinav: hii guys

Harish - Expert: Disk Output cache is the new method in 2.0 by which you can store the cache to your disk

Joshi: hi all

Harish - Expert: it is enabled at the page level as follows:-

Harish - Expert: <%@ OutputCache Duration="3600" VaryByParam="none" DiskCacheable="true" %>

Harish - Expert: Notice the DiskCacheable="true" property

Harish - Expert: this ensures that the cache is saved to the system such that it can survive application restarts and memory fill ups

Dhrumit: You mean to say in stead of memory the cached data stored on the disk of server?

Harish - Expert: exactly

Harish - Expert: not instead of

Harish - Expert: in addition to

Harish - Expert:

Harish - Expert: you have to specify an additional attribute

Harish - Expert: <diskCache enabled="true" maxSizePerApp="2" />

Dhrumit: Ok

Harish - Expert: that is maxSizePerApp

Harish - Expert: In the above settings, the per-application disk usage limit is set to 2 megabytes, as specified in the maxSizePerApp attribute

Harish - Expert: Disk caching is turned on by default for all pages. To turn disk caching off, specify DiskCacheable=false in the directive on the page.

Harish - Expert: HI ABHINAV

Harish - Expert: HI JOSHI

Chatanya: This is page level attribut or application level that we have to specify in web.config

abinav: hii to

abinav: ok

Harish - Expert: if you want for your applicaiton level, set it at the web.config

Harish - Expert: <?xml version="1.0"?> <configuration> <system.web> <caching> <outputCache> <diskCache enabled="true" maxSizePerApp="2" /> </outputCache> </caching> </system.web> </configuration>

Dhrumit: I think logically it should be at application level in most of the cases

Harish - Expert: you are right

Harish - Expert: but in some cases, you wont require it for all pages

Harish - Expert: anyway, even if you specify in the web.config you can over ride it at the page level

Harish - Expert: the hierarcy of overloading is machine.config - web.config - page

Chatanya: ok

Harish - Expert: where page stands the highest priority and takes the relevant mechanism specified there

Dhrumit: Ya thats right.

Joshi: ya hi

Dhrumit: Ok can we move to next mechanism? we still have to cover security features ...

Harish - Expert: sure

Harish - Expert: I will ask you all one question

Harish - Expert: in .NET 1.x version

Harish - Expert: if you want to enable caching for only portions of your page, what you will do

Harish - Expert: ?

Chatanya: that can be done using fragment caching

Dhrumit: yes fragment caching

Harish - Expert: absolutely

Harish - Expert: but just imagine you have to break your pages into segments

Harish - Expert: for achieving this simple mechanism

Harish - Expert: right?

Chatanya: but I have heard in ASP.net there is provision for if if you do not want to implement caching for a prortion of a page but enable it for whole page

Harish - Expert: that is precisely what i m coming at

Harish - Expert: Post Cache Substitution

Joshi: a portion of a page can be done

Harish - Expert: You have the Post Cache Substitution where you can delegate a call back to the Method which you specify using the Response.WriteSubstitution Method to make the particular section dynamic.

Dhrumit: Could not understand harish. Can you give one example?

Harish - Expert: sure

Harish - Expert: static string GetCurrentDate(HttpContext context) { return DateTime.Now.ToString(); }

Harish - Expert: have this method in your page

Harish - Expert: this would return the current time right?

Dhrumit: right

Joshi: yes

Harish - Expert: <%@ OutputCache Duration="60" VaryByParam = "none" %>

Harish - Expert: this is to enable caching for 60 seconds

Harish - Expert: now in the aspx page, we will have Time: <%= DateTime.Now.ToString() %>

Harish - Expert: just a label time to which i assign the current date time

Harish - Expert: then, i have another label which reads "Exact time"

Harish - Expert: to that, i assign this function

Harish - Expert: <% Response.WriteSubstitution(new

HttpResponseSubstitutionCallback(GetCurrentDate)); %>

Harish - Expert: notice the HttpResponseSubstitutionCallBack

Harish - Expert: the function Getcurrentdate is called back everytime the page is requested

Harish - Expert: despite the page being cached

Harish - Expert: which would result in the "Exact time" label showing you the exact time

Harish - Expert: well, showing time is not the great thing

Harish - Expert: but you can use this for methods in your page where you want each time the

function to be implemented

Harish - Expert: you dont need to go for usercontrols

Harish - Expert: you dont need to for breaking down your page

Harish - Expert: as simple as that

Dhrumit: Ok. So this is specially to un-cache some part of the cached page, right?

Harish - Expert: exactly

Harish - Expert: you also have a server control to achieve this

Harish - Expert: aspubtitution control

Harish - Expert: < aspubstitution id="Substitution1" methodname="Provide Method Name

Here" runat="Server"> </aspubstitution>

Harish - Expert: oops

Harish - Expert: < asp: substitution id="Substitution1" methodname="Provide Method Name

Here" runat="Server"> </asp: substitution>

Harish - Expert: whatever i gave as Response.WriteSubstitution

Harish - Expert: you can instead specify the method name in the above <Asp : substitution tag

Harish - Expert: and still achieve the same functionality

Harish - Expert: just different flavours

Dhrumit: Ok.

Bijoy: That's a nice functionality

Harish - Expert: Caching is important to leverage the full power of .NET

Harish - Expert: if you are targetting Realworld applications that server millions of users

Harish - Expert: its always important you use Caching to improve the performance of your

application

Dhrumit: Humm. Thats right.

Chatanya: How to use caching in Stck exchange application?

Harish - Expert: Believe it, its there in Whidbey

Joshi: this is nice

Harish - Expert: Stock exchange application - my advise is, dont use caching

Harish - Expert: Shall we move to Security Features

Bijoy: But I think there is a potential hidden questions, stock exgs cater to millions of users

Bijoy: it would be a nice case study

Harish - Expert: Thats right. Caching is a subject of PHD for some people

Harish - Expert: there has always been reasearch on this

dotnetparam: What are the new Security features in ASP 2.0

Joshi: just throw some idea on thi s

Dhrumit: What is Cache Configuration?

Harish - Expert: Cache Configuration is the property by which you set the Cache expiration

policy

Harish - Expert: duration

Harish - Expert: dependency and all those setings

Harish - Expert: does that answer your question

Harish - Expert: NEW SECURITY FEATURES IN ASP.NET 2.0

Dhrumit: Oh ok i think its some diff mechanism. Lets go to the security.

Harish - Expert: We are running out of time

Harish - Expert: Well, I will ask you quick questions

Harish - Expert: How do you implement role based authorisation in ASP.NET 1.1

Harish - Expert: or for that matter ASP.NET 1.0

Harish - Expert: the reason for asking questions is to make interactive

Harish - Expert: some of the members seems to be lost in their way

Bijoy: Probabily through manual coding

dotnetparam: through web.config 's Authorisation

Harish - Expert: i would be Glad if they are following

dotnetparam: tag

Harish - Expert: you are right

Harish - Expert: but just imagine the nuber of lines of code you write

Harish - Expert: YOu need to set the Role

Harish - Expert: you need to set the role cookie

Harish - Expert: you classify the user based on his role

Harish - Expert: and then you have to check this role in each page

Harish - Expert: right?

Dhrumit: yes.

Harish - Expert: You dont need to do that, ASP.NET 2.0 takes care of that

Bijoy: yes

Joshi: oh grt

Harish - Expert: To configure Roles / Permissions you have the Website Administration Tool

Harish - Expert: Its one point from where you can specify the Permissions / Roles / Access

level

Joshi: where

Harish - Expert: i cannot show you the page over here

Harish - Expert: but i can give you links at the end of the session

Harish - Expert: where you can see the website administration settings

Joshi: k

dotnetparam: ok

Harish - Expert: its as simple as selecting ":Allow" or "Deny" from a dropdownlist

Dhrumit: Ya right. I saw this tool once in one of the MSDN session. Its really nice.

Harish - Expert: and specify the rights

Harish - Expert: Oh thats great

Harish - Expert: The other great security feature is that

Harish - Expert: Today, to implement Form Based Authenticatin in a cookieless scenario, it is

very difficult

Harish - Expert: in 2.0, your same code will work both for cookieless as well as cookie based

scenario

Harish - Expert: if cookies are enabled, ASP.NET intelligently uses the straight forward method

of storing the cookies in the user's system

Harish - Expert: if cookies are disblaed, ASP.NET is still brilliant

Harish - Expert: it will append the cookie as a chunk of code to the URL

Harish - Expert: the chunk of encrypted code is encrypted

dotnetparam: fine

Harish - Expert: The good thing is that

Joshi:

Harish - Expert: you dont need to change the functionatliy

Harish - Expert: I think Joshi is reading his Credit Card Bill

Harish - Expert: or his Wife's Email

Joshi: k

Harish - Expert: Some of the cool things are

Harish - Expert: Login Control

Harish - Expert: Change Password

Harish - Expert: Forgot Password

Harish - Expert: Logged In View

Harish - Expert: Login Control you can just drag and drop into your login.aspx and use its built-

in APIs to perform a login check

Harish - Expert: Change Password - obviously for changing the password

dotnetparam: great

Dhrumit: Ya right. And it automatically generates database for that. By default in Access in Data

folder right?

Harish - Expert: thats right

Harish - Expert: However, it is configurable

Harish - Expert: you can cahnge it to your own database

Dhrumit: One more is Sign Up page i think...

Chatanya: but in cookie less implementation

Harish - Expert: the Good thing is that you can leverage all the Controls and extend them

Joshi: just i am thnking that its making our life easy

Harish - Expert: obviously

dotnetparam: what is Logged in View

Chatanya: they are still lacking with one problem size of querystring

Harish - Expert: Say Login control by default has a user name and passowrd control

Harish - Expert: however, if you want to add your own field such as a Domain, you can still do

that

Dhrumit: dotnetparam, Logged in View is show ur status on top of the page like Hello Username,

and display a link to logoff, right Harish?

Harish - Expert: Querystring well, if you see cookieless scenario you can append a lot of

information

Harish - Expert: so i think that answers the query

dotnetparam: ok

Harish - Expert: Logged in View is where you say Welcome <username>

Harish - Expert: and if you are not logged inm, Sign in from <a href="login.aspx">here</a>

Harish - Expert: we allw ould implement this in typical scenarios

dotnetparam: so that is shown on each page by default...without any coding efforts

Harish - Expert: absolutely

Harish - Expert: it is configurable from design view

Harish - Expert:

dotnetparam: ok

Dhrumit: Any other security feature left, Harish?

Harish - Expert: there are lots

Harish - Expert: membership and role management

Harish - Expert: the Membership API ships with the ASP.NET 2.0

Harish - Expert: and you can utilize it for Member creating, role management, personalization

etc.,

Dhrumit: ok.

Harish - Expert: today, if you have to do personalization you have to store everything in

session, cache or some strange ways to identify the user

Harish - Expert: in 2.0 you dont need to do that

Chatanya: so where all that will be stored on server or on user machine as form of cookie

Harish - Expert: it will be in Database

Harish - Expert: but it will be faster than you expect

Harish - Expert: the Role Manager automatically manages User specific information

Harish - Expert: You can also extend it to include your own customizations

Harish - Expert: GUYS, WE ARE ALMOST RAN OUT OF TIME

Harish - Expert: so you can ask questions

Chatanya: How they are implementing it in database

PETERR: hi harish how to implement passport auth. in our applications

Harish - Expert: to implement passport authorization you must download the passpord sdk available

Harish - Expert: its a paid service

Harish - Expert: but for testing purposes, you can use it freely.

Harish - Expert: when you go to real time deployment there are some licensing requirements.

Harish - Expert: once you download and install the passport sdk,

Harish - Expert: you can leverage its methods such as HexPUID to identify the logged in user

Harish - Expert: and you automatically get the BEAUTIFUL SIGN IN and SIGN OUT logos

Dhrumit: I have a question but its not related with topics ....

PETERR: ok cool

Harish - Expert: oh sure

PETERR: ty harish

Dhrumit: How to use TELNET from .net code? Is there any standard dll available?

Harish - Expert: it is availble

Harish - Expert: i can mail you the link if you can give your mail id

Dhrumit: Fro FTP I found one dll code on microsoft site in vb.net. And i used it successfully.

Harish - Expert: thats Great

Dhrumit: That ll be great. You can mail me on Dhrumit_Desai@Keane.com

PETERR: one more thing, harish if i use passport auth all my users have to register with microsoft.com is that right

Harish - Expert: not necessary

Harish - Expert: any email address which is passport enabled will work

Harish - Expert: but ideal scenarios would be using the Hotmail MSN or Passport email address which are, by default Passport enabled

Harish - Expert: i have my company email address and still can use to sign in to MSN Messenger

Harish - Expert: i just had to register it with the passport service

PETERR: where will the details of the user stored

Harish - Expert: the passport service, would verify it is a valid email addess and then register

PETERR: so the details will be stored in the microsoft end, am i making sense

PETERR: meaning the user details

Chatanya: So Is it ok to give your details to third party?

Joshi: this is like common data base maintennence from diiferent platforms

Joshi: is it right harish

Harish - Expert: its like your Master ACArds

Joshi: thats vat i mean to say ..

Harish - Expert: yeah

PETERR: so the details will be stored in the microsoft end, am i making sense
