Network
Use Ruby’s network classes to let your scripts speak basic protocols such as TCP and UDP as a client, a server, or both. These libraries provide socket access to a variety of Internet protocols and classes that make access to those protocols easier. You can even crawl up the protocol stack and find support for higher-level protocols like FTP, HTTP, IMAP, and so on. All have an intuitive, transparent interface that won’t get in your way. This is the largest group of libraries and one of the most frequently used.
Oh, and don’t worry. There’s support for doing web
programming through the CGI, CGI::Cookie and
CGI::Session classes.
