Request is Componentized so you can attach data to the request. Here's
how it works ...

Define an interface and an implementation:

    class IFoo(Interface):

    class Foo:
        __implements__ = IFoo,

To associate some Foo data with the request do:

    foo = Foo()
    foo.bar = 'bar'
    request.setComponent(IFoo, foo)

And finally, do something like this to retrieve the data from the

    foo = request.getComponent(IFoo)

Cheers, Matt
