HyperText Transfer
Protocol,
HTTP is a set of standards that let users of the
World Wide Web to
exchange information found on web pages. When a user wishes to access a
web page it is commonly required that http:// be placed before the
address, allowing the browser to know it is going through HTTP. For example,
the full address for Computer Hope is
"http://www.computerhope.com".
However, today many Internet browsers
allow users the ability to specify the domain
"www.computerhope.com"
and default to HTTP.
- HTTP/0.9 was the first version of the HTTP.
- HTTP/1.0 is specified in RFC
1945
- HTTP/1.1 is specified in RFC 2616.
- HTTP commonly utilizes port
80, 8008, or 8080.

as plaintext, the information is

security.
- HTTPS uses port
443 to
transfer its information.
- HTTPS is the same as HTTP/1.1 and is defined in RFC
2616.
