Thanks for the quick reply. I was mistaken about MSIE's capabilities, my apologies.

However, HTTP does indeed permit this, via the CONNECT method as described in RFC 2616:

This specification reserves the method name CONNECT for use with a proxy that can dynamically switch to being a tunnel (e.g. SSL tunneling 44).

RFC 2817 details usage of the CONNECT method:

5.2 Requesting a Tunnel with CONNECT

A CONNECT method requests that a proxy establish a tunnel connection on its behalf. The Request-URI portion of the Request-Line is always an 'authority' as defined by URI Generic Syntax 2, which is to say the host name and port number destination of the requested connection separated by a colon:

CONNECT server.example.com:80 HTTP/1.1
Host: server.example.com:80

To "chain" two proxies, one simply sends a CONNECT to the first proxy, requesting to connect to the second proxy. Once the tunnel is established, normal GET requests with a fully-qualified URI can be used. This works.

I know HTTP, I just want to coax Perl into speaking this portion of the specification. Can I, using the standard modules? I searched LWP documentation for any mention of the CONNECT method, but couldn't find any occurances... are there any other HTTP modules which fully support the HTTP/1.1 spec, or do I have to write my own?
