Next: Client Request Up: HTTP Previous: HTTP Contents Establishing a ConnectionThe first step in this pavan of courtly love is that of establishing a connection between the client-suitor and the suited-server. The client-suitor starts this process by using a URI to query the suited-server. Usually this opens a TCP/IP connection between the two lovers-to-be over port 80. However, the HTTP 1.1 specification does not require that a TCP/IP connection be used. To quote the ``word of the lord'' in these matters, i.e. RFC 2626 section 1.4 paragraph 8: ``[the HTTP protocol can be] implemented on top of any other protocol on the Internet, or on other networks. HTTP only presumes a reliable transport; any protocol that provides such guarantees can be used...'' So, the lovers could conduct their courtship under the aegis of the postal system, a telegraph, or carrier pigeons.
