httpd-2.0: what happened to /manual ?
I just built a httpd-2.0 and installed.
Funnily, the index page from http://server/ is also displayed under
http://server/manual/ (but not when invoking
http://server/manual/index.html or http://server/manual/index.html.en).
Does that mean that mod_alias is wrong, or mod_negotiation, or
mod_userdir? I am confused. The behavior is really *very* funny.

I forgot to mention that the Alias is completely ignored, as it seems.
I get a 404 response when trying to access anything under manual/
and it's logged with filename .../htdocs/manual (although I do have an alias
to .../manual)

In the meantime, I get this when trying to access the /manual alias:
[Fri Oct 12 09:26:17 2001] [error] [client 172.25.124.236] File does not exist:
/home/apa20/htdocs/manual/, referer: https://apache.mch.fsc.net:8443/

This sounds like an error in the new directory_walk... that we aren't
dealing with /manual/ correctly (loosing a trailing slash, it sounds like.)
I'll investigate later this eve or tommorow morning, more news as it happens.

All ready reverted, Greg. Additional patches to request.c may have eliminated
some of the other problems you observed, Greg. Please provide a detailed
example if you continue to see recursion.

Sorry about that. I did verify that some directory scenarios worked
before commiting, but didn't test this URL. I'll take a look.

By a process of elimination I've narrowed it down to rev 1.68 of
server/request.c. That is, if I reverse it I get served the manual as expected.
The change is a little over my head at the moment though:
------------------------------------------------------------------------
revision 1.68

prevent near infinite subrequest recursion with mod_negotiation enabled.
This can happen if there is a partial match between a bad URI and a
file with a variant extention.
ap_sub_req_lookup_dirent has apparently been generating bogus subrequest
URIs for ages, but they used to be ignored. Once we started calling
ap_process_request_internal for all subrequests, they started causing
problems. Make it explicit that rnew->uri is to be ignored for this type
of subrequest.

Yeah, I'm seeing this too. Does anyone know what's going on here?
