18. Internet Protocols and Support

The modules described in this chapter implement Internet protocols and support for related technology. They are all implemented in Python. Most of these modules require the presence of the system-dependent module socket, which is currently supported on most popular platforms. Here is an overview:

webbrowser		Easy-to-use controller for Web browsers.
cgi		Common Gateway Interface support, used to interpret forms in server-side scripts.
cgitb		Configurable traceback handler for CGI scripts.
wsgiref		WSGI Utilities and Reference Implementation
wsgiref.util
wsgiref.headers
wsgiref.simple_server
wsgiref.validate
wsgiref.handlers
urllib		Open an arbitrary network resource by URL (requires sockets).
urllib2		An extensible library for opening URLs using a variety of protocols
httplib		HTTP and HTTPS protocol client (requires sockets).
ftplib		FTP protocol client (requires sockets).
gopherlib		Gopher protocol client (requires sockets).
poplib		POP3 protocol client (requires sockets).
imaplib		IMAP4 protocol client (requires sockets).
nntplib		NNTP protocol client (requires sockets).
smtplib		SMTP protocol client (requires sockets).
smtpd		Implement a flexible SMTP server
telnetlib		Telnet client class.
uuid		UUID objects (universally unique identifiers) according to RFC 4122
urlparse		Parse URLs into components.
SocketServer		A framework for network servers.
BaseHTTPServer		Basic HTTP server (base class for SimpleHTTPServer and CGIHTTPServer).
SimpleHTTPServer		This module provides a basic request handler for HTTP servers.
CGIHTTPServer		This module provides a request handler for HTTP servers which can run CGI scripts.
cookielib		Cookie handling for HTTP clients
Cookie		Support for HTTP state management (cookies).
xmlrpclib		XML-RPC client access.
SimpleXMLRPCServer		Basic XML-RPC server implementation.
