IIS Application Initialization for IIS 7.5 enables website administrators to improve the responsiveness of their Web sites by loading the Web applications before the first request arrives. By proactively loading and initializing all the dependencies such as database connections, compilation of ASP.NET code, and loading of modules, IT Professionals can ensure their Web sites are responsive at all times even if their Web sites use a custom request pipeline or if the Application Pool is recycled...

IIS Application Request Routing (ARR) 3 enables Web server administrators, hosting providers, and Content Delivery Networks (CDNs) to increase Web application scalability and reliability through rule-based routing, client and host name affinity, load balancing of HTTP server requests, and distributed disk caching. With ARR, administrators can optimize resource utilization for application servers to reduce management costs for Web server farms and shared hosting environments.

Bit Rate Throttling, an IIS Media Services extension, saves money on network costs by metering the download speed of media and data files. For media, Bit Rate Throttling accomplishes this by automatically detecting the encoded bitrates of 11 common media formats, such as Windows Media Video (WMV), Flash Video (FLV), and MPEG-4 (MP4), and then throttling the response to the client. For any other file or MIME type, Bit Rate Throttling allows administrators to configure custom throttling rules.

Live Smooth Streaming, an IIS Media Services extension, enables adaptive streaming of live events to Smooth Streaming clients, such as Microsoft Silverlight. Using HTTP to deliver live events takes advantage of the scale of existing HTTP networks and keeps content close to your viewers, making true HD (720p+) a realistic option for live web broadcasts. The additional advantage of using HTTP-based delivery for live events is that the existing HTTP infrastructure also drastically increases live...

Smooth Streaming, an IIS Media Services extension, enables adaptive streaming of media to Silverlight and other clients over HTTP. Smooth Streaming provides a high-quality viewing experience that scales massively on content distribution networks, making true HD 1080p media experiences a reality.

The IIS Smooth Streaming Format SDK 1.0 Beta 2 provides documentation, tools, and samples you can use to create software programs that package encoded video and audio bitstreams for on-demand and live Smooth Streaming scenarios. In addition, the SDK supports the encryption of content using Microsoft PlayReady DRM.

IIS URL Rewrite 2.1 enables Web administrators to create powerful rules to implement URLs that are easier for users to remember and easier for search engines to find. By using rule templates, rewrite maps, .NET providers, and other functionality integrated into IIS Manager, Web administrators can easily set up rules to define URL rewriting behavior based on HTTP headers, HTTP response or request headers, IIS server variables, and even complex programmatic rules. In addition, Web administrator...

Web Deploy (msdeploy) simplifies deployment of Web applications and Web sites to IIS servers. Administrators can use Web Deploy to synchronize IIS servers or to migrate to newer versions of IIS. Web Deploy Tool also enables administrators and delegated users to use IIS Manager to deploy ASP.NET and PHP applications to an IIS server.

Web Playlists is an IIS Media Services extension that provides developers and hosters unprecedented control of how media content is delivered to users. Powerful customization features make it possible to monetize media delivery scenarios by inserting in-stream or pre-roll video ads and dynamically determine the content to be delivered based on the session history and configurable server-side rules.
