thanks for the reply, that would not be too practical as it would need 
to be distributed over 50 pages (its a packaged app that I am doing some 
integration on) here is the code that would need to be included on each 
page:

$visitor_host = @getHostByAddr( $ip );
$ip                                = $_SERVER['REMOTE_ADDR'];
$referer               = $_SERVER['HTTP_REFERER'];       // URL of 
calling page
$refer                = $_SERVER['HTTP_REFERER'];       // URL of 
calling page
$rhost                   = $_SERVER['REMOTE_HOST'];           // host 
name of visitor
$ruser                   = $_SERVER['REMOTE_USER'];        // Remote 
Username if available
$user                        = $_SERVER['PHP_AUTH_USER'];             
//current user
$user_agent             = $_SERVER['HTTP_USER_AGENT'];
$uri                             = $_SERVER['REQUEST_URI'];
$user                         = $_SERVER['PHP_AUTH_USER'];
$proxyIP                     = $_SERVER['HTTP_X_FORWARDED_FOR'];
$proxyhost                = $_SERVER['HTTP_X_FORWARDED_HOST'];
$proxyserver            = $_SERVER['HTTP_X_FORWARDED_SERVER'];
$request_method     = $_SERVER['REQUEST_METHOD'];
$server_protocol     = $_SERVER['SERVER_PROTOCOL'];
$url                          = $_SERVER['HTTP_HOST']. $_SERVER[PHP_SELF];

$sql  =  "INSERT INTO MyTracker VALUES('',now(), 
'$ip','$referer','$user_agent','$rhost','$ruser','$ruri','$request_method','$server_protocol','$proxyIP','$proxyserver','$proxyhost','$url', 
'$visitor_host');";

$results  =  mysql_query ( $sql);

as you can see, that would get pretty unwieldy in a short time, 
expecially if I needed to change something in this call...
