Have you looked at urls lately? http:/example.org/blah/blah https:/example.org/foo/bar git:/github.com/my/wonderful/project smb:/mypc/username/documents The first bit of the url is the protocol - guess what - it explicitly chooses between http / hhtps / git / whatever. It runs above tcp/udp, not tcp80/443. (I've never seen an smtp:/ or imap:/ url, but I guess they could easily be formulated.) Cheers, Wol
