From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Description of problem: This is the httpd bug from http://issues.apache.org/bugzilla/show_bug.cgi?id=21348 "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." URL: http://www.mail-archive.com/dev@httpd.apache.org/msg16088.html Patch: http://www.mail-archive.com/dev@httpd.apache.org/msg16088/windows-update.diff I backported the patch listed in the diff as a part of my own RPM and rebuilt it. It works as expected then. Version-Release number of selected component (if applicable): httpd-2.0.47-10 How reproducible: Always Steps to Reproduce: Load up httpd with the proxy enabled. Go to Windowsupdate.microsoft.com. Watch it error out with error #0x80072f76. Rebuild with the above patch and it will work fine. Additional info:
This should be fixed in 2.0.48 - can you try the 2.0.48 updates? http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/1/i386/
I first pulled the httpd-2.0.48-1.2 RPM from http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/1/i386/ and tried it unpatched and it doesn't work. When that happened, I got the SRPM and the patch I referenced from CVS did not make it in to protocol.c. After adding it, it worked just like 2.0.47 did. But 2.0.48 is still broken in this regard by default.
Fedora Core 1 is maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thanks! NOTE: Fedora Core 1 is reaching the final end of support even by the Legacy project. After Fedora Core 6 Test 2 is released (currently scheduled for July 26th), there will be no more security updates for FC1. Please use these next two weeks to upgrade any remaining FC1 systems to a current release.
Closing per lack of response to the previous comment. Note that FC1 and FC2 are no longer supported even by Fedora Legacy. If this bug still occurs on FC3 or FC4, please assign to that version and Fedora Legacy. If it still occurs on FC5 or FC6, please reopen and assign to the correct version.
