User data across multiple domains - using sessions?

[CarlitoBrigante]

We have a website and a vbulletin forum, and we would like to let users login also from the website so that they are automatically logged in also in the forum.

Problem is, we have different domains for the forums and the website (for example websitenetwork.com, websiteforum.com). So, we cannot set cookies for all domains simultaneously, as this wouldn't work with new browsers.

I was thinking - how can I do this with php sessions? Somebody did it?

Thank you!

Seems like alot of work, and not somthing someone is going to do for free unless they also need this.

You might want to look into a service request.

Perhaps you can have an I-Frame so the 2nd site sets its own cookie.
