Session destroy after logout.php > help ??

After logout.php, it goes back to logon.php screen which I want. But when I use browser's back button, it still lets me in.

After the logout.php URL changes to this
URL

What ?logmeout bit at the end of my URL here ? what does it do?

Here is the logout code for the page
--------------------------------------------------------------------------
<?php
// start the session
session_start();
?>
<html><head>


<title>iCollectIt</title>


<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">


</head>

<body topmargin="2">
<table width="95%" border="0">
<tr>
<td width="247" height="62" valign="top"><img src="../Logos/ICI-Banner.gif" width="243" height="56"></td>
<td width="527" align="left" valign="middle" nowrap> <blockquote>
Rare
and Collectable 
CD's, DVD's and Vinyl's
</blockquote></td>
<td width="11"> </td>
</tr>
<tr>
<td height="3" colspan="2" valign="top" bgcolor="#006699"></td>
<td> </td>
</tr>
<tr>
<td height="18" colspan="2" valign="top"> <div align="center">.
. . . make us an offer we can't refuse</div></td>
<td> </td>
</tr>
</table>

<table width="75%" border="0" align="center">
<tr>
<td colspan="7">
<?
if(!isset($_REQUEST['logmeout'])){
echo "<center><center>Are you sure you want to logout? ";
echo "<center><a href=logout.php?logmeout>Yes</a> | <a href=javascript:history.back()>No</a>";
} else {
session_destroy();
if(!session_is_registered('first_name')){
echo "<center>You are now logged out!</center> ";

echo "<center>You may login again.</center> ";
include 'login_form.html';
}
}
?>
</td>
</tr>
</table>
 
</body>
</html>

you need to set the page caching to 0... i.e. so that the page expires ones it has been loaded, and you cannot therefore go back to it.

Thnks for your input.

I went had a look at some of the help topics on this. It is too diffucult to follow. All I need to tell it to expire once the user logs out so that page is not remembered.

Is the a sample perhaps you could suggest . I don't even know what the coplete code supplosed to look like.

I don't know any PHP but it'll be the same as ASP.. you need to add a page expire header. Simply google, "expire header php" (without quotes) - that'll get you going in the right direction
