This is the first question that really needs an answer.

I will assume that you have a normal proxy, since if it were your
web pages you could accomplish this filtering easier.

Rabbit has no session handling in itself.
You can try to add cookies or something else, but it will not work nice
for all clients and cookies are per domain so you can not use cookies
reliably. The only thing I can think of is to try to include javascript,
but that will also be quirky and will not work well for images or plain
text documents.

Perhaps you can mix cookies and javascript and hope that your users
have both of them enabled.

I can not say that I know of a good way to do this.

Not sure if that will work for complex nested frames.

Rabbit is not a servlet engine so you will never be able to do that.

Also note that what you are trying to do is the opposite of rabbits
goal, adding extra content make the download go slower.
Although I want to make rabbit easy to use for general filtering this
kind of filtering is not high on my TODO-list. There may be easier tools
to use out there, but I do not know about them.

Have fun
