I've copied it from gitweb URL's. They were wrong. I just fixed it too.

The http transport should be used only as the last resort, where some corporate
firewalls are configured to block git. The usage of http is less
efficient than git, and require to enable a per-repository hook that runs
every time a repository is updated. The hook updates some files that http 
transport needs.
