Session Cache

programming
1

I am using session cookie to make sure that my website members login to access certain privileges. However, everytime the back button is used, the browser always RELOADS the entire page. If I remove my session in the script, the cache works well enough. How shall I fix it so that the browser does not have to reload the page everytime.

Here is the code I use at the first lines of my page:


<?php
session_name('YourSessionID');
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

the codes at the body:

 
<body>
<?php
$id=$_SESSION['sess_id'];
?>
<table width="750" align="center" cellpadding="0"  cellspacing="0" bgcolor="#FFFFCC"><!--DWLayoutTable-->
  <tr>
    <td colspan="3" bgcolor="#FFFFFF">
