this is such a basic question, that I higly recommend that you look at
http://www.plope.com/Books/2_7Edition

in short: the request is a dictionary like object that gives access to
all data pertaining to the communication between the client and the server.

you can easily have a detailed look at it with a page template like the
following:

<html>
<body>

<div tal:content=structure "context/REQUEST" />

</body>
</html>

The REQUEST is always available as part of the "current" object - usually
referenced as 'context' in PythonScripts, 'context' or 'here' in ZPTs
or when using 'self' within the implemetation of a Zope class. There is
nothing specific about CMF here.

If the method expects a REQUEST object (for whatever reason)
you have to pass it in. A method of a persistent object could also
take the REQUEST from 'self'....
