The modules described in this chapter implement Internet protocols and support for related technology. They are all implemented in Python. Some of these modules require the presence of the system-dependent module socket, which is currently only fully supported on Unix and Windows NT. Here is an overview:
| cgi | Common Gateway Interface support, used to interpret forms in server-side scripts. |
| urllib | Open an arbitrary object given by URL (requires sockets). |
| httplib | HTTP 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). |
| telnetlib | Telnet client class. |
| 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 request handler for HTTP servers. |
| CGIHTTPServer | This module provides a request handler for HTTP servers which can run CGI scripts. |
| asyncore | A base class for developing asyncronous socket handling services. |
