Microsoft External Cache Version 1 for IIS 7, developed by Microsoft Corporation, is an extension that enables Internet Information Services (IIS) 7 to store and retrieve cached HTTP responses from an external cache instead of relying solely on the in-process output cache. By offloading cached content to a shared, out-of-process, or distributed cache, it improves scalability and performance in web farm environments, increases cache hit rates across servers, and reduces memory usage on individual nodes.
The module integrates with IIS 7’s output caching framework, honoring standard vary-by rules, cache profiles, and expiration policies. It can be configured through IIS Manager or configuration files and works alongside existing IIS features and ASP.NET applications. Typical use cases include accelerating frequently requested static or dynamic content, smoothing load during traffic spikes, and centralizing cache management and invalidation across multiple servers. An external caching infrastructure is required to use this module effectively.
Microsoft External Cache Version 1 for IIS 7 is developed by Microsoft. The most popular version of this product among our users is 1.1. The name of the program executable file is InetMgr.exe.
