Cookie setting/deleting issue

[Todd88]

Alright so I have a website where users get referrals. If someone visits the site using a referral link, their is a cookie placed so that the user that visited the site signs up under the person that is in the cookie.

Here is a scenario where there is an issue:

Person A visits the site under Person B's referral link. Therefore, a cookie with person B's username is placed on Person A's computer.

Now, if Person A visits the site under Person C's referral link, Person B's referral link is still the cookie.

I have tried to remove the cookie and it works but not instant. Like in the scenario I just gave you, Person A would SEE Person B's cookie, and if the page refreshed, then Person C's cookie would show up.

Is there any way around this? I know PHP is a server side language and that might be the overall issue, but if it's not, please help me! Thanks in advance.

1. Shouldn't the first referrer get credit?
2. You can just add a conditional override to wherever the user sees who referred them. If you're going to set a cookie on that page load, then simply override what ever data you base on that cookie.
