windowsupdate-site over proxy failed





------- Additional Comments From cvig@raw-io.com  2003-07-26 22:02 -------
Same problem here using various Windows versions (XP, 2000, 98 SE) behind a
Windows 2000 machine running Apache 2.0.46 (Win32). A patch was posted on the
dev mailing list back on March 24, 2003. The patch fixes this issue which occurs
because:

"Apache2 proxy seems to drop Content-Length header from replies to HEAD
requests. This is very bad for Microsoft's Windows Update system (and against
HTTP spec). The problem is caused by CONTENT_LENGTH output filter setting
Content-Length header to zero because there is no body data. Later on Apache
removes Content-Length header if it has value 0.

The attached patch fixes the problem in CONTENT_LENGTH output filter by
preventing it from modifying the content length of a reply to HEAD request.

The attached patch is against HEAD of APACHE_2_0_BRANCH as of this morning."

I would apply the patch myself but I do not have the compiler required for the
Win32 build of Apache.
