Network and Web Libraries
Ruby provides two levels of access to network services. At a low
level, you can access the basic socket support in the underlying
operating system, which allows you to implement clients and servers for
both connection-oriented and connectionless protocols. These are
documented in the next section.
Ruby also has libraries that provide higher-level access to
specific application-level network protocols, such as FTP,
HTTP, and so on. These are documented starting
on page 482.
Finally, the
CGI libraries, documented beginning on page 497,
provide server-side developers with a
convenient interface for developing Web applications.
