HTTP transfer protocols | |
======================= | |
Git supports two HTTP based transfer protocols. A "dumb" protocol | |
which requires only a standard HTTP server on the server end of the | |

As a design feature smart clients can automatically upgrade "dumb" | |
protocol URLs to smart URLs. This permits all users to have the |
