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...
