httptunnel doesn't handle a 2nd connection

[Szabó Péter]

Hi!

I think I have found a bug in httptunnel. I set up a pair
of `hts -s' and `htc -s', and the first connection goes
smoothly. But when I abort the htc with Ctrl-<C>, and start
a new `htc -s', it just hangs, and data is not transferred.
I think this is a bug in httptunnel, or at least a bad
default configuration.

My suggested solution is that using ?crap= to distinguish
connections at the server-side, and if a connection with
new ?crap= is found, the old one should be aborted
immediately, without a timeout, and the new one should be
handled.

Another suggestion: it should be explicitly stated in the
documentation that httptunnel cannot handle multiple
connections at the same time: the 2nd connection will just
hang till long after the 1st one has exited.

Best regards,
