Because I see the result page. All print_login prints different pages.

there is nothing extraordinary, just few prints and nothing else.

Does the output you send depend on something external, like a parameter
from CGI.pm?

You could be accidentally creating a closure. Also, keep in mind that
PerlRun only clears globals within the main script. If you use any
modules that have globals in their own namespaces, those do not get
cleared by PerlRun.

Well, the code you've shown so far doesn't seem like it could produce
the results you're talking about, so we really need you to show us a
test case to give you further help. If you can reduce your script down
to a very simple one that demonstrates the problem and post it here, we
can probably see what's wrong.

Can you come up with two simple test scripts that you can reproduce the
problem with? We fail to guess a possible reason for this behavior. We need to
be able to reproduce the problem to analyze it.

PerlRun doesn't cache scripts it compiles at all. Registry does.

see above.

You don't need to emulate it. Just run it online. You can use Apache::Test to
setup a test if you really want to. But if you give us 2 scripts and the
instructions how to reproduce the problem we will do that. (e.g., request
script 1 once and then script 2, and then ...).
Also try to reproduce the problem while running under 'httpd -X'.
