how long does $_POST last?

[Chris-the_dude]

Does the $_POST array hold any values if you are coming from anywhere but a submitted form?

Lets say I have a page called form.php where it's got a tag
<form action="submit.php" method="post">

I know that when I submit, and go to submit.php that $POST array variables will exist as I have defined them in the form elements, but if I then refresh submit.php or go to a new page, will $POST still hold any values?

in most browser if u refresh a submit page you will see a pop up saying if you want to re-send data, so the answer technically is yes

however if you go to a different page the variables will be lost
