Not easily. Is the servlet in Java? You might want to consider just
embedding JGit[1] and using that. JGit will let your servlet install
an implementation of its PreReceiveHook interface where you can
inspect the parsed protocol data, decide what to do, and reject it or
allow it through.

To reject before it makes it to git-http-backend you need to parse the
incoming data stream, decode the commands, and then forward the
unparsed stream to git-http-backend. If you are in Java you might be
able to reuse some of the JGit classes to help you parse the protocol.
Maybe. Those classes weren't really built to be used on their own.
