Sorry, just replying to myself since I realised I left off something

You might notice that the CONNECT verb gives you a built-in generic 
proxy capability. Just, for example, connect to your work HTTP proxy and 
say 'CONNECT chat.isp.com:194' and you've got a connection to an IRC 
network; maybe your work doesn't want that.

For this reason, your average HTTP proxy is going to default to having a 
filter that the port section of the CONNECT request must be 443.
