My question is how do I hide the session_id in the address bar of the browser.
I pass a session in two diferent ways
1:
<input type="hidden" name="session_id" value="<? echo("$session_id") ?>">
2:
<a href="http://form_add_documents_procedure.php?session_id=<? echo $session_id ?>" >
the result is something like this
http:\www.dhl.com\form_add_documents_procedure.php?session_id=120939040
