Use only what you need
IIS is built with a completely modular architecture, on top of rich extensibility APIs. This enables you to easily add, remove and even replace built-in IIS components with custom modules, specifically suited for customer needs. Use only what you need. Customize and add new features, such as Application Request Routing and URL Rewriting through free IIS Extensions.
Speed up your Web site through built-in dynamic caching and enhanced compression. IIS provide the fastest performance for static and dynamic Web content through powerful HTTP compression and deeper integration with request serving from the Windows kernel for SSL Web sites. Implement a scalable Web infrastructure with HTTP-based load balancing and intelligent request handling and routing.
IIS maximizes Web server security by default with minimal Web server footprint and automatic application isolation. IIS offers performance sandboxing through CPU throttling, which reduces the probability of a runaway application. In addition, IIS offers greater application isolation by giving worker processes a completely unique identity and sandboxed configuration by default, further reducing security risks.
