The protocol - recognizes three parts to a request: - - 1. One line identifying the request type and path - 2. An optional set of RFC-822-style headers - 3. An optional data part - - The headers and data are separated by a blank line. - - The first line of the request has the form - - <command> <path> <version> - - where <command> is a (case-sensitive) keyword such as GET or POST, - <path> is a string containing path information for the request, - and <version> should be the string "HTTP/1.0" or "HTTP/1.1". - <path> is encoded using the URL encoding scheme (using %xx to signify - the ASCII character with hex code xx). - - The specification specifies that lines are separated by CRLF but - for compatibility with the widest range of clients recommends - servers also handle LF. Similarly, whitespace in the request line - is treated sensibly (allowing multiple spaces between components - and allowing trailing whitespace). - - Similarly, for output, lines ought to be separated by CRLF pairs - but most clients grok LF characters just fine. - - If the first line of the request has the form - - <command> <path> - - (i.e. <version> is left out) then this is assumed to be an HTTP - 0.9 request; this form has no optional headers and data part and - the reply consists of just the data. - - The reply form of the HTTP 1.x protocol again has three parts: - - 1. One line giving the response code - 2. An optional set of RFC-822-style headers - 3. The data - - Again, the headers and data are separated by a blank line. - - The response code line has the form - - <version> <responsecode> <responsestring> - - where <version> is the protocol version ("HTTP/1.0" or "HTTP/1.1"), - <responsecode> is a 3-digit response code indicating success or - failure of the request, and <responsestring> is an optional - human-readable string explaining what the response code means. - - This server parses the request and the headers, and then calls a - function specific to the request type (<command>). Specifically, - a request SPAM will be handled by a method do_SPAM(). If no - such method exists the server sends an error response to the - client. If it exists, it is called with no arguments: - - do_SPAM() - - Note that the request name is case sensitive (i.e. SPAM and spam - are different requests). - - The various request details are stored in instance variables: - - - client_address is the client IP address in the form (host, - port); - - - command, path and version are the broken-down request line; - - - headers is an instance of email.message.Message (or a derived - class) containing the header information; - - - rfile is a file object open for reading positioned at the - start of the optional input data part; - - - wfile is a file object open for writing. - - IT IS IMPORTANT TO ADHERE TO THE PROTOCOL FOR WRITING! - - The first thing to be written must be the response line. Then - follow 0 or more header lines, then a blank line, and then the - actual data (if any).
