git push does not work properly on git over http server

Hi, we have set up a git server over http in our office following this documentation: http://www.kernel.org/pub/software/scm/git/docs/howto/setup-git-server-over-http.txt

I have made git clone locally in another PC: git clone http://git.vsilicon.net/linux-2.6.22.y.git/

And have started developing and creating a new branch with several commits:

git checkout -b visstrim v2.6.22

Then I would like to push my new branch to the remote server:
git push --all origin
Fetching remote heads...
  refs/
  refs/tags/
  refs/heads/
'refs/heads/visstrim': up-to-date
'refs/heads/master': up-to-date

But then I do:
git branch -r
  origin/HEAD
  origin/master

And new branch hasn't gone remote.

I have tested curl succesfully and dav with cadaver and everything goes fine, I can read/write/lock without problems.

If I check apache log in LEO I can find that command "git push --all origin" only does GET http commands:

Shouldn't it show PUT commands since git push is supposed to upload data to remote server?

Any idea? I have been looking for this problem through the net for several days with no success.
