Class BaseRequestHandler

Known Subclasses:

StreamRequestHandler

Base class for request handler classes.

This class is instantiated for each request to be handled.  The
constructor sets the instance variables request, client_address
and server, and then calls the handle() method.  To implement a
specific service, all you need to do is to derive a class which
defines a handle() method.

The handle() method can find the request as self.request, the
client address as self.client_address, and the server (in case it
needs access to per-server information) as self.server.  Since a
separate instance is created for each request, the handle() method
can define arbitrary other instance variariables.
