Session works but yields new data only on new login

[swatisonee]

Hi, I use sessions and have not had an issue on anything other than this. When i update a form, the data gets recorded in the db but if i refresh using the browser button, i dont see the new data. i have to sign out and when i sign in afresh the updated or new data is visible.

What could be the reason and how do i solve it ?

All my scripts have the foll. in the header :

<?

session_cache_limiter('public');
include ("../include/session.php");
require ("../include/bottom.php");
include ("../include/ticker.php");

if(!isset($_SESSION['userid'])){
 echo "<center><font face='Verdana' size='2' color=red>Sorry, Please login and use this page </font></center>";
 exit;}

$userid = $_SESSION['userid'];

?>

session.php is simply session_start . I put in the cache limiter because i couldnt get the back button to work - ie the session data would not remain if i used the back button and then came back to the page.

Hi,

I am not sure why it would be a session issue. How do you retrieve the data from the database? Can you view the data if you move to another page, and return to the page that is supposed to show the info from the database?

Unless you store the info in the session arays: What does a print_r($_SESSION) give you?

It is because you are allowing caching with the 'public' directive. Turn caching off. Use header cache controls to make sure that intermediate proxies do not cache the pages either.

hi,

I turned caching off and replaced it with

header("Cache-Control: public");
include ("../include/session.php");  and so on

Now i get to see the data but when i hit the back button of the browser , i get an "page cannot be displayed " / "information not entered" screen.

I dont have any problems in viewing data and then using the back button to move back and forward.

This only happes when data is to updated and then i want to view that the modified data.

Thanks !
