Session Problem

[molecul3]

I've created a session on all my files... below is a sample...

<?php
session_start();
header(&quot;Cache-control: private&quot;//IE 6 fix
header (&quot;Expires: Mon, 26 Jul 1997 05:00:00 GMT&quot;
header (&quot;Last-Modified: &quot; . gmdate(&quot;D, d M Y H:i:s&quot . &quot; GMT&quot;
header (&quot;Cache-Control: no-cache, must-revalidate&quot; // HTTP/1.1
header (&quot;Pragma: no-cache&quot;
if ($_SESSION['lname'] == &quot;username&quot {
}
else
{
die(&quot;Please <a href=\&quot;index1.htm\&quot;> Login </a>As Lecturer First!<br>&quot;

}
?>

the problem here is there is an error when I code files that have session and I include a file that has a session also. The 2 sessions seem to clash. An error occurs. How do I fix this problem?

I don't understand what you are asking for.

A single browser has only 1 session at a time. You can only have 2 sessions if you have different browser instances, so I don't know how you come to the conclusion that 2 sessions clash.

Also, be aware that you can set the cache control mechanisms with the session:

Please explain more about the error.

Knowing the error might be handy, too.

Hmm... let me try to explain.

I have to files. File1.php and File2.php
Both these files have the same session code as stated on top. The problem here is when i code File1.php, i use the include(&quot;File1.php&quot;

This is where the error occurs as the file has in a way become one and there are now 2 sessions... therefore an error is produced.

Here's a suggestion:

1. Put your session starting code into a separate file, I'd call it a module.
2. use include_once() to include the module in the files.

This will assure if you include a file within another file the components loaded with include_once('filePathetc') will only included once.
