From what I understand, as soon as you try to use the body of a request
using Apache2::Request, it reads it all in. Which might play havoc with
the idea of using a Filter to modify a request / inject a body to replay
an old post request.
However, without that complication it may be possible. Have you looked
at the filter documentation on perl.apache.org? Particularly the
examples in this section:
http://perl.apache.org/docs/2.0/user/handlers/filters.html#Input_Filters
My suggestion would be to try it and see what happens. Filters are one
aspect of mp2 that it seems like a lot of people haven't really used. I
personally have used OuputFilters for a bunch of things, but i haven't
used InputFilters at all. I'm also not familiar enough with how OpenID
works to really be able to comment on what you're trying to do.
