#!/usr/bin/perl # 5.6.1998, Sampo Kellomaki <sampo@iki.fi> $usage = <<USAGE Usage: ./https-proxy-snif.pl *listen_port* *dest_machine* *dest_port* E.g: ./https-proxy-snif.pl 4443 www.bacus.pt 443 This proxy allows you to observe the protocol talked by your browser to remote https server. Useful for debugging http headers etc sent in this dialogue as well as capturing the requests for later automating the task. The proxying is not perfect: the client will see different certificate than actually sent by server. You will be able to launch only one simultaneous connection (set you browser to attempt only one at a time) because it is iterative server, keep-alives are not handled at all, etc. Remeber: you must have cert.pem and key.pem in the current working directory. Example: ./https-proxy-snif.pl 4443 www.bacus.pt 443 Then enter https://localhost:4443/ in Netscape Location prompt.
