Updated HTTP Referrers code will do the following:

• http:// will be added if not present (for consitency!)
• www. will be added to base urls if not present (for consitency!)
• http://www.site.com/name?=text will become http://www.site.com
• Each additional referral will bump up the count
• Each additional referral will bump up the last date

Essentially your index.php file will have the referer code removed to an includes file to handle referrals.

You will have a cleaner, better base of referral information!

Download from HireAmerica (sorry but downloads require simple registration) and enjoy!

PS - This might get included in NukeSentinel (e.g., Tracked Referrers) in the future!
