corkscrew - Tunnel TCP connections through HTTP proxies

=head1 SYNOPSIS

  corkscrew  PROXY PROXYPORT TARGETHOST TARGETPORT [AUTH_FILE]

=head1 DESCRIPTION

corkscrew is a simple tool to tunnel TCP connections through an HTTP
proxy supporting the CONNECT method. It reads stdin and writes to std-
out during the connection, just like netcat. It can be used for
instance to connect to an SSH server running on a remote 443 port
through a strict HTTPS proxy.
