FIX: IIS 6.0 serves stale content if your Web site has both an IP address and host headers set

In Microsoft Internet Information Services 6.0, if your Web site is configured for both an IP address and host headers, any change that you make to the static content does not appear immediately.

This problem occurs because of the way that the content is stored in the Http.sys cache.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Server 2003 Service Pack 1.

When you store a cache entry in the Http.sys cache, the Http.sys cache uses a "host header + IP address" token. However, the Http.sys cache does not return a "host header + IP address" token in the parsed (also known as cooked) URL of a request. Therefore, when you try to flush a cache entry by using the parsed URL of a request, the flush does not succeed.
