SYMPTOMS

When you use behaviors to download information from a file to an HTML document, and Static Compression is turned on in Microsoft Internet Information Services (IIS), the data that is downloaded to the HTML document does not always appear. Typically, the document loads as expected on the first attempt. However, dynamic data may not appear when you try to download it again.

CAUSE

This problem occurs because Microsoft Internet Explorer always reads compressed data as being cached, even if the cache-control setting specifies a different value.
