Ok. Can you explain this in more detail? I understand the concept you
are suggesting but I can't picture how to do this in PHP.
Something like:
If there isn't a session, start one and redirect to the same page WITH the
session id, otherwise just continue the session.
In theory, you should always get a session ID in the URL of startpage.php.
But I can't stress enough, this is all theory -- the code hasn't been tested
at all... nor particularly thought through :)
startpage.php:
? // untested code
if(!isset(session_id()))
{
session_start();
header(Location: startpage.php?PHPSESSID=.session_id())
}
else
{
session_start();
}
?

[PHP] session lost when back button hit?
I have two pages, page one links to page two via a form button. The browser does not accept cookies. On page two I create a session variable with: $_SESSION[id] = 1; But if I hit the back button to go back to page one $_SESSION[id] is not set. If I hit the reload button on page one it is still not set. How can I get a session var to stay set when someone hits the back button? Jc PS I have session.auto_start ON and enabled trans-sid -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

HI make ser youre using session_start() before performing any action on sessions, also make sure you´re registering properly the variables. -Mensaje original- De: Jean-Christian Imbeault [mailto:[EMAIL PROTECTED]] Enviado el: viernes, 16 de agosto de 2002 9:43 Para: [EMAIL PROTECTED] Asunto: [PHP] session lost when back button hit?

Did you see my PS at the end of my question? PS I have session.auto_start ON and enabled trans-sid I don't need seesion_start() and I don't need to register the variable since I am setting it directly with $_SESSION[id] = 1 If I am wrong about this please correct me, I'm still new to sessions.

RE: [PHP] session lost when back button hit?
By any chance, is page one the entrance page to your application? I.e. is there a session id in either the query string of the page URL or was there one passed to it via a POST? Without cookies enabled, there is no way to allow users to use the back button to go back to the entrance page while maintaining the session. One (hackish) solution to this is to cause the entrance page to immediately redirect to itself using either PHP's header function, or a meta refresh. Your goal here is to make it so that hitting back from a secondary page would take you to the post-refreshed entrance page which has the session ID.

Users just enter the URL in the location bar, for example, and come in. Without cookies enabled, there is no way to allow users to use the back button to go back to the entrance page while maintaining the session. Really? I just turned cookies and javascript off and then visited Amazon.com. I added an item to my cart, hit the back buttonall way back to the entrance and then checked my cart ... lo-and-behold the item was in my cart still. How did they do that? One (hackish) solution to this is to cause the entrance page to immediately redirect to itself using either PHP's header function, or a meta refresh.
