Ok, I'm getting closer but still not there yet.  I've
added a filter like so:

PerlInputFilterHandler Apache::RedirectPost

Its purpose is to grep the POST data for certain key
value pairs and if it matches, set some flag (cookie
or header).  Then a handler down the chain can, in
theory, take some action based on this flag.

I also have these declarations:

PerlAccessHandler Apache::GateKeeper
PerlTransHandler Apache::DefaultTrans
PerlHandler Apache::Content

I've been able to successfully capture the POST data
without removing it from the chain.  Problem is, it's
too late.  From what I've been able to gather from
printing to the error log, the chain looks like this:

PerlTransHandler --> PerlAccessHandler --> PerlHandler
--> PerlInputFilterHandler

I thought the filter was accessed before the
response-handler. What am I doing wrong?
