Description Anders Steinlein 2005-10-20 01:26:03 UTC
I almost pulled my hair out having spent several hours trying to figure out why 
a vanilla installation simply would not work; requests seemed to loop ("Opening 
page..." in IE forever and ever) and no access log entry, error, notice or any 
indication of what was wrong were sent to the logs. Then I found the 
Win32DisableAcceptEx directive, which solved the problem.

I've read the documentation for the directive, so I know the bug itself might be 
related to something external to Apache (although exiting virus scanners, 
firewalls etc on my computer didn't help). How widepread is this problem? If the 
bug itself is completely out of Apache's control, I suggest some enhancements 
which might help others encountering the same problem:

- Sniff the behaviour of AcceptEx() upon starting Apache (if this is feasible), 
and log any potential problems found. (I did not encounter the error condition 
mentioned in the Win32DisableAcceptEx directive documentation - NO indication of 
a problem was given to me.) 
- Add the directive to the Windows-distributed httpd.conf in the WinNT MPM 
section (commented out by default, I would guess), making it clear to the user 
that there might be a potential problem lurking.
