SYMPTOMS

When you try to open a Microsoft Office document or a PDF file by typing an HTTPS URL for the document in the Address bar of Internet Explorer 6 Service Pack 1 (SP1), you may receive the following error message:

Unable to download.

Internet Explorer was unable to open this site. The requested site is either unavailable or cannot be found. Please try again later.

CAUSE

This issue occurs if the server sends a "Cache-control:no-store" header or sends a "Cache-control:no-cache" header.

RESOLUTION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
