Description:
------------
I have an aplication in PHP Version 4.2.2 working and stop working in PHP Version 4.3.1 because of session variables...

Both versions have register_globals ON

In the 4.2.2 if i do echo $var; it would be recognized as the POST on any form field registered

In the 4.3.1 i have to do echo $_REQUEST["var"]; or call the function import_request_variables; or... 

CFG of 4.3.1:

<INPUT type=TEXT maxLength=40 size=15 name=login0 value=10>
<INPUT style='FONT-SIZE: 8pt; FONT-FAMILY: Arial' type=submit value=Send>
