That helps alot. Can you explain the following...

Code:
$ua->proxy(['http', 'ftp'], 'http://proxy.sn.no:8001/');

Is there a http and ftp protocol because either protocol could be passed via proxy?

Code:
$ua->proxy(['http', 'ftp'], 'http://proxy.sn.no:8001/');

This means any http or ftp requests will be proxy'd via http://proxy.sn.no:8001/

For HTTP, there is a special mechanism called tunneling. Its not a different protocol, just that the GET/POST requests will be slightly different, so that actual requests can be piggy-backed.

Is that 'tunneling' the HTTP/1.1 persistent connection, where you can send many GET and POST and the return stream has ids to let you sort them out?

SSH has tunneling, but URLs that use it do not disclose it. It can only support ftp with extra tricks . . . .
