When doing a clone by https (reverse proxied to http) the first

How does the ?service=xxxx get translated in to the action performed

If you are using the git-http-backend CGI, it will interpret the
service

No, using plain jane http and webdav. This server is not "allowed" to use cgi processes.

tag and start smart-http. See "git help http-backend" for details on
plugging it into Apache.

Cloning/fetching does not use DAV at all; it is only for non-smart
pushing (and I would not recommend setting it up; the smart protocol
spoken by git-http-backend does pushing much more efficiently, and is
better maintained).

I ask because I have 2 projects, one works the other does not.

Should have said I get a 404 versus 200, see below.

I am using httpd-2.0.52-49.ent.centos4 and git-1.7.9.6-1.

I am not even sure what to tell more about or where to look next.

If you haven't set up git-http-backend, then git is just going to fetch
the remote repo's data directly over http. So the usual advice for
accessing something via http would apply (check the server's access and
error logs, try hitting it with a web browser, etc).

If you set GIT_CURL_VERBOSE=1 in your environment, git will spew a lot

That’s what I did before mailing out the first time. I tried to summarize the contents, but I will paste the relevant portions below.

of debugging information about what http requests it is making. That
might give you a clue (you haven't said anything about what does not
work, so I can't be more specific).

Below are two traces, the first one is the one that does not work, the second does. I cannot see any differences on the web server for the two directory trees.
