Hello,
This is true and I actuallly tried this but what happens in the
servlet will do the post as it should but will NOT forward
the user to the resulting page. Even if you went ahead and redirected on
to the external site after the post, you still will not have the posted data.
I think javascript may come in handy here but have to deal with cross platform issues.
