use cookies to track sign ups?

[Anon]

Hello

Any help on this appreciated!

I have a banner on my webpage for site XXX.

Everytime someone clicks on it I get $0.01

I am also supposed to get $$ if someone signs up with XXX (after they clicked on my banner.)

The banner uses a HTML link like:
http://www.mcash.com/cgi-bin/agents.cgi?website=XXX&memberid=my_id
This link redirects you to site XXX and tracks the click.

I understand how mcash keeps track of every click, but how do they know if the person who clicked on my banner signed up for site XXX? Especially if site XXX is not on the same server as mcash?

Any explanation or help greatly appreciated!

Thank you.

This is not at all PHP related, and I don't know why I'm answering this, but here goes...

They simply look at the remote IP.
That is also how they notice when people are using scripts to fake the hits and signups.
When you enter the site though the link on your banner, they record your IP. If a from that IP proceeds to register within X minutes of coming to the site, then you are credited. If nobody registers within X minutes, the IP is erased again. This is to prevent unfair crediting from people who share IP's through dialup-lines and DHCP.
