Setting and Retrieving Cookies

[y4hdesigns]

This may not be the place for this question, but...

We're looking into creating a single registration and logon system for vBulletin and the rest of our site.

To do so, we'd like to understand more about how the PHP is used to generate and call the cookie for logon.

Can someone help? Maybe just pointing to the right file would help so we can dig into it.

Our thought was to create a cookie with logon info for the rest of the site and for vBulletin and use that to log users on. We haven't decided whether to populate directly into the mySQL db for registration or to replicate from our other db at this point.

Any suggestions/comments would be helpful.

Thanks.
