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):
pass
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
request:
foo = request.getComponent(IFoo)
Cheers, Matt
