To check it is working correctly once configured, use the following:

  $ curl -si https://git.qemu.org/git/capstone.git/info/refs?service=git-upload-pack | grep --binary-files=text '^Content-Type'


Once configured correctly that should display:

   Content-Type: application/x-git-upload-pack-advertisement
