STATUS

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.

MORE INFORMATION

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.
