Customer stories

These case studies highlight how real developers were able to benefit from the features of Windows Internet Explorer 8:

WebMynd
"Publishers want their websites and services exposed as widely as possible, and we can now meet that need. Working with Internet Explorer means the majority of people can use our software."

bwin International
"We saved about 50 percent of the time we would have needed to develop, test, and certify our site for earlier versions of Internet Explorer—or any browser that does not adhere to web standards."

State of California Department of Technology Services
While creating a new CMS, the DTS also implemented several enhancements to the California Government portal home website to take advantage of the browser features introduced in Internet Explorer 8, such as Web Slices and Accelerators. Web Slices allow individuals to subscribe to portions of the website and, with a single click in the Favorites Bar, view the latest updates. Accelerators simplify the steps to search, map, send, translate, or share content from a webpage with one click.

  • Side-by-side rendering engines

  • X-UA-Compatible switch that allows developers to specify which rendering engine they want to use

Features that increase the stickiness level of your site

Drive more traffic to your site while giving customers richer experiences. Create Accelerators and Web Slices that keep your site and services just a click away no matter where your customers are on the web.

  • Use Accelerators to provide a quick and easy way to call back into your web service, so users can use it anywhere they are on the web.

  • Use Visual Search and Search Suggestions to increase the value of search results. Users know that they’re getting what they’re looking for quickly and easily.
