@echopoint @OmgImAlexis what do you guys think?

[gabrielcsapo]

this should satisfy the original requirements of #26

Looks good to me. Check your # .. 26 is this pull #. ;)

Bah spoke too soon. All http.ServerRequest type references should probably be http.IncomingMessage, depending on the context in which the variable is being assigned from. i.e. if the variable is the first parameter in the http.request event, then it should be an http.IncomingMessage instead. If the variable is assigned from the return of the http.request function, then it should be an http.ClientRequest type. ;)
