One Script Can't Edit Other Script's Cookie

[curtiss]

As I mentioned in another thread, I'm working on a PHP login script to work with YaBB.

I've basically got everything working, so that both scripts recognize each other's cookies (which are identical, except for the expiry date/time). However, I can't seem to get them to play nicely with each other when destroying the cookies.

A cookie generated by my PHP script cannot be edited (or therefore destroyed) by YaBB, and a cookie generated by YaBB cannot be edited by my PHP script.

As you can see from the following images, both sets of cookies are identical, except for their expiry dates/times.

The cookies set by YaBB:


The cookies set by my script:

Cookies are usually restricted to domain and maybe path. Not to a technology. When we ran Coldfusion on the mainsite, I picked up cookies from vbulletin as well. Are you absolutely sure about your code?
