HTTP is Hyper Text Transform Protocol and is transmitted
over the wire via PORT 80(TCP). You use HTTP when you are
browsing the web.


HTTPS (Hypertext Transfer Protocol over Secure Socket
Layer, or HTTP over SSL) is a Web protocol developed by
Netscape and built into its browser that encrypts and
decrypts user page requests as well as the pages that are
returned by the Web server. HTTPS is really just the use of
Netscape's Secure Socket Layer (SSL) as a sublayer under
its regular HTTP application layering. (HTTPS uses port 443
instead of HTTP port 80 in its interactions with the lower
layer, TCP/IP.) SSL uses a 40-bit key size for the RC4
stream encryption algorithm, which is considered an
adequate degree of encryption for commercial exchange.
