No. The request bean is of type HttpServletRequest... the specification
is not very clear on this point but if you check further down in the
spec you will see in the section "Implicit Variable" (just before
"Additional Functionality") that the implicit variable request is of
type HttpServletRequest. Well it's confusing. But IMO, the request bean
is of type HttpServletRequest and that's the way I did in my own
implementation.
Anyway the request object that you get in the processRequest method is
the one you need and it will contain all the information you need.

It can do LOOP-DISPLAY/INCLUDEIF and EXCLUDEIF too... I think it can be
very useful when you use the nested bean like:
<DISPLAY PROPERTY="request:params:myParam" PLACEHOLDER="You should
provide a myParam!">
