Doubt on Filters

[muthu kumaran]

Hi All,
This is regarding answer for Q5 in Chapter 13(filters and wrappers)
in HFSJ.
Here one of the answers for the question , which about filters are true ?
is
Filters may be used to create request and response wrappers..

I don't understand the context

How can a filter be used to create a reqest/response wrapper? ( It just uses a request/response wrapper)

IF that answer is supposed to be correct then for that matter any user-defined class can be used to create a wrapper for request/response.

Can anyone clear my doubt??

Thanks
Muthu

Hi Marc,
I don't understand what you meant by that post.
My name is of course "Muthu" ( a common name in Southern India).
If you have any doubts on whether its a fictious name you can contact any
south Indian to verify it..( even a google search wud do)
I personally feel a bit bad about this post..
