About HyperText Transfer Protocol (HTTP)
The HyperText Transfer Protocol (HTTP) is a protocol (a set of rules that describe
how information is exchanged on a network) that allows a web browser and a web
server to "talk" to each other using the ISO Latin1 alphabet, which is ASCII with
extensions for European languages.
HTTP is based on a request/response model. The client connects to the server and
sends a request to the server. The request contains the following: request method,
URI, and protocol version. The client then sends some header information. The
server's response includes the return of the protocol version, status code, followed
by a header that contains server information, and then the requested data. The
connection is then closed.
