I was just thinking of one thing. Please follow me, and tell me if this could help:

1 - two different domains need the same user authentication. They are mywebsite1.com and mywebsite2.com.
2 - I have another website, named mynetwork.com. I create virtual subdomains web1.mynetwork.com and web2.mynetwork.com, redirecting respectively to mywebsite1.com and mywebsite2.com.
3 - Now, if I try to set a cookie from mywebsite1.com for *.mynetwork.com, would it work on both websites?

Thanks!

Had another idea... but maybe it's not doable.

What if I include an image in all my websites coming from the same forum's domain. Let's say I have mywebsite2.com and in it I put something like

include("http://mywebsite1.com/printimage.php");

This script will print an image AND will set a cookie for mywebsite2 when the user login in mywebsite2...
