in reply to HTTP::Proxy and Trillian

After running your code:
$ echo -ne 'CONNECT http://localhost HTTP/1.0\n\n' | nc localhost 8089 HTTP/1.1 501 Not Implemented Date: Mon, 13 Oct 2003 17:31:42 GMT Server: libwww-perl-daemon/1.26 Content-Length: 46 Method CONNECT is not supported by this proxy
So it is HTTP::Proxy

Makeshifts last the longest.
