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 | |

| 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. | |
