PHP Page Logging Problem

[Tricky]

I have a script "logger.php" which includes the following code:

PHP Code:

if ($HTTP_VIA)
        {
            *****proxy = "Y";
            if (strpos($HTTP_X_FORWARDED_FOR,',')) 
            { 
                $HTTP_X_FORWARDED_FOR = substr($HTTP_X_FORWARDED_FOR,0,strpos($HTTP_X_FORWARDED_FOR,',') ); 
            }
            *****addy = $HTTP_X_FORWARDED_FOR;
            if(*****addy == "")
                *****addy = getenv("REMOTE_ADDR");                    
        }
        else
        {
            *****proxy = "N";
            *****addy = getenv("REMOTE_ADDR");
        } 


If I execute the script standalone it returns:
proxy = Y and hitaddy is my "REAL" IP address

If I include the script in another file (HTML) with:

PHP Code:

<?PHP include "/logger.php"; ?>

It returns
Proxy = N and the hitaddy is the "PROXY" NTL one!

Why? and how do I fix it!?

What happens if you put the snippit of code directly into the new page?

It works - Just noticed that the profanity checker has blanked my code!! the ***** is really $ hits without the space!!!

running the code alone sets the values correctly as in my 1st post
