Have you looked at urls lately? |
| 13 |
|
| 14 |
http:/example.org/blah/blah |
| 15 |
|
| 16 |
https:/example.org/foo/bar |
| 17 |
|
| 18 |
git:/github.com/my/wonderful/project |
| 19 |
|
| 20 |
smb:/mypc/username/documents |
| 21 |
|
| 22 |
The first bit of the url is the protocol - guess what - it explicitly |
| 23 |
chooses between http / hhtps / git / whatever. |
| 24 |
|
| 25 |
It runs above tcp/udp, not tcp80/443. |
| 26 |
|
| 27 |
(I've never seen an smtp:/ or imap:/ url, but I guess they could easily |
| 28 |
be formulated.) |
