Am I right? Is there any > documentation on what an http proxy is supposed to implement. The easiest way to test this is to knock together a quick little server, set your browser to use localhost as a proxy, and see what requests you get. You're correct as regards most requests, but HTTPS is more complicated. All your proxy will see is a CONNECT request; you have to accept or deny on the basis of address alone, you don't get the whole URL (for obvious reasons). But that aside, yes, you'll normally get a request that looks pretty similar to what the origin server would get. ahh, happy memories of MUDding through a local proxy that permitted CONNECT on more ports than 443... and even happier memories of getting port 23 opened to direct access, hehe...
