help with config settings to get me started

[stephdowney]

was wondering if anyone could help me with this .....i'm working on a computer not using local host but iss and therefore i need to change these config settings but not sure what to....?

// setting up the web root and server root for
// this shopping cart application
$thisFile = str_replace('\\', '/', __FILE__);
$docRoot = $_SERVER ("csweb");





$webRoot = str_replace(array($docRoot, 'library/config.php'), '', $thisFile);
$srvRoot = str_replace('library/config.php', '', $thisFile);

define('WEB_ROOT', $webRoot);
define('SRV_ROOT', $srvRoot);

any ideas?
thanks
