Sessions over subdomains

Can it be done?

I have a site written in PHP with a members section that uses sessions.
Fairly ordinary stuff, but the sessions always end up being cleared when
I move between subdomains on the site.

Some Googling threw up some vague references to cookies, but nothing
really conclusive.

Has anybody successfully got around this little problem?

Ta,

Dan

I had a similar problem that drove me totally bonkers, until I spent a
long time using trial and error, Googling to no avail, then eventually
sussed it!

This might not work for you, but in my case the solution was to start
the session at the top level, i.e:

http://mysite.com

NOT a subdomain like:

http://www.mysite.com

If I started it at the top, then it would work lower down. However, the
converse is not true. When I initiated the session here:

http://www.mysite.com

The values were not available here:

http://mysite.com

Can you start your sessions in http://mysite.com/anypage.php?

You have to set the domain attribute of the cookie correctly.

A domain mysite.com would match hostnames subdomain.mysite.com as well as
www.mysite.com

That looks like a brilliant idea, but it didn't work for me

Thanks anyway, Charles. I appreciate it!

No problem. I figured it might not suit you, but hopefully give you
some pointers.
