SYMPTOMS
After you submit a request in an Active Server Pages (ASP) Web page that returns (or caches) an HTML Component (HTC) file on your computer, when you next submit a request in that ASP page, Microsoft Internet Explorer generates an additional If-Modified-Since GET request to the server. This problem occurs even though the HTC file has not expired.
