Embperl always puts the POST data into %fdat, when they are present

This has nothing to do with Apache. Your browser simply uses the same uses
the URL of your form as ACTION e.g. when you request your form with
x.epl?b=1
your browser will act as if you had wrote
<form method=post action"x.epl?b=1">

I don't know if this is your problem, but there is a problem with some
browser, because they behave different. Not all browser uses the form url as
default action. MSIE does it, but not all Netscape versions.

For the above reasons: Yes!
Just write
<form method=post action="$ENV{SCRIPT_NAME}">
This makes sure the form calls always itself.
