After receiving and interpreting a request message, a server responds with an HTTP response message:
A Status-line
Zero or more header (General|Response|Entity) fields followed by CRLF
An empty line (i.e., a line with nothing preceding the CRLF)
indicating the end of the header fields
Optionally a message-body
The following sections explain each of the entities used in an HTTP response message.
