creating a session variable on every page

[laredotornado]

Hi,

I'm using PHP 4.4.4 with Apache 2.2. What I want is that if a
customer visits any page of the top level directory of my site with
this string passed in the URL's query string, "RID=xxx", I would like
a session variable called "RID" with the value "xxx" to be created.
However, I would like to avoid putting this code

session_start();
if (!empty($_REQUEST['RID'])) {
$_SESSION['RID'] = trim(strtoupper($_REQUEST['RID']));
} // if

on every page in my top level directory. Does anyone know a more
efficient way?

Thanks, - Dave

Two things:

1. There is an Apache auto_prepend directive you can put in htaccess (or
httpd.conf).

2. Use mod_rewrite to redirect certain?/all? files to a script that does
your session check and then includes the requested file
