+\section{Built-in module \sectcode{httplib}}
+\stmodindex{httplib}
+\index{HTTP}
+
+This module defines a class which implements the client side of the
+HTTP protocol. It is normally not used directly --- the module
+\code{urlllib} module uses it to handle URLs that use HTTP.
+\stmodindex{urllib}
+
+The module defines one class, \code{HTTP}. An \code{HTTP} instance
+represents one transaction with an HTTP server. It should be
+instantiated passing it a host and optional port number. If no port
+number is passed, the port is extracted from the host string if it has
+the form \code{host:port}, else the default HTTP port (80) is used.
+If no host is passed, no connection is made, and the \code{connect}
+method should be used to connect to a server.
+
+Once an \code{HTTP} instance has been connected to an HTTP server, it
+should be used as follows:
+
+\begin{enumerate}
+
+\item[1.] Make exactly one call to the \code{putrequest()} method.
+
+\item[2.] Make zero or more calls to the \code{putheader()} method.
+
+\item[3.] Call the \code{endheaders()} method (this can be omitted if
+step 4. makes no calls).
+
+\item[4.] Optional calls to the \code{send()} method.
+
+\item[5.] Call the \code{getreply()} method.
+
+\item[6.] Call the \code{getfile()} method and read the data off the
+file object that it returns.
+
+\end{enumerate}
+
+\code{HTTP} instances have the following methods:
+
+\begin{funcdesc}{set_debuglevel}{level}
+Set the debugging level (the amount of debugging output printed).
+The default debug level is \code{0}, meaning no debugging output is
+printed.
+\end{funcdesc}
+
+\begin{funcdesc}{connect}{host\optional{\, port}}
+Connect to the server given by \var{host} and \var{port}. See the
+intro for the default port. This should be called directly only if
+the instance was instantiated without passing a host.
+\end{funcdesc}
+
+\begin{funcdesc}{send}{data}
+Send data to the server. This should be used directly only after the
+\code{endheaders()} method has been called and before
+\code{getreply()} has been called.
+\end{funcdesc}
+
+\begin{funcdesc}{putrequest}{request\, selector}
+This should be the first call after the connection to the server has
+been made. It sends a line to the server consisting of the
+\var{request} string, the \var{selector} string, and the HTTP version
+(\code{HTTP/1.0}).
+\end{funcdesc}
+
+\begin{funcdesc}{putheader}{header\, argument\optional{\, ...}}
+Send an RFC-822 style header to the server. It sends a line to the
+server consisting of the header, a colon and a space, and the first
+argument. If more arguments are given, continuation lines are sent,
+each consisting of a tab and an argument.
+\end{funcdesc}
+
+\begin{funcdesc}{endheaders}{}
+Send a blank line to the server, signalling the end of the headers.
+\end{funcdesc}
+
+\begin{funcdesc}{getreply}{}
+Complete the request by shutting down the sending end of the socket,
+read the reply from the server, and return a triple (\var{replycode},
+\var{message}, \var{headers}). Here \var{replycode} is the integer
+reply code from the request (e.g. \code{200} if the request was
+handled properly); \var{message} is the message string corresponding
+to the reply code; and \var{header} is an instance of the class
+\code{rfc822.Message} containing the headers received from the server.
+See the description of the \code{rfc822} module.
+\stmodindex{rfc822}
+\end{funcdesc}
+
+\begin{funcdesc}{getfile}{}
+Return a file object from which the data returned by the server can be
+read, using the \code{read()}, \code{readline()} or \code{readlines()}
+methods.
+\end{funcdesc}
