request.form tends to contain useful information.

The principal is object representing the user. What do you mean by 
accessing user credentials?

Typically you deal with a derived interface from that, IBrowserRequest:

zope.publisher.interfaces.browser.IBrowserRequest

This one defines 'form'

This also derives from IHTTPApplicationRequest:

zope.publisher.interfaces.http.IHTTPApplicationRequest

This one defines 'cookies', 'headers', 'URL', and a whole bunch of methods.

All this also derives from 
zope.publisher.interfaces.IApplicationRequest, which defines more stuff.

It's all very much factored, which indeed makes it harder to find stuff 
in one place. Our admin interface should eventually help, and so should 
a grok reference.
