Well, to be pedantic, you can't set ssh to tunnel only HTTP (or, at
least, I'm not aware of any implementation for which you can); the
closest you can get is to set ssh to tunnel only port 80.  ssh is blind
to what protocol you run over tunneled connections.  (Except for X
tunneling, which is a special case and is requested differently
anyway.)

It is?  That's an implementation defect, then.  There is no need for
port forwarding to be bidirectional; assuming implementations that
support it (which includes all implementations I know of), it's
entirely possible to forward port 1234 on the client to port 2345 on
the server without forwarding anything the other way - or conversely.

Of course, any given forwarded connection is capable of carrying
traffic in both directions, but that's true of any TCP connection.
