Cookies across domains

Anon

I am working on a site that has 5 sub-sections. Each can function as it's own site and has a unique domain name, but much of the data is universal (across all sites.) Such as a users registration for posting comments, and the like. I use cookies for convience to save logon/password (actually thats all I use them for). Currenlty each domain name requires a different cookie to be set, so that a person would require 5 cookies to have their password saved on the "network".

I have looked around but I am unable to locate exactly what I need - which is to set a cookie that can bind to all my adresses - or is this really not possible?

Thanks,
Scott

Hi,
a couple of days ago I had a similar problem and as far as I know the browser can't read cookies saved by another domain (specification of cookies).

While IE (my current version 5.5) allows me to read cookies from a page belonging to a different subdomain, Netscape 4.7 doesn't allow this either. I decided to store the required informations in a db...but maybe someone else can help you/me.

if you guys are talking about sub-domains (ie www.sub.mydomain.com) you could do the following
setcookie("name","value",time()+x, "/","sub.mydomain.com",0);

it should (I'm saying 'should' since I never tested it) make the cookie avail...you could also use $SERVER_NAME instead of typing all that server names.

hope that helps.

Unfortunately the domain names are not third level, myname.domain.com, but infact are different doname names: mysite-fps.com, mysite-console.com, and others that are more acute to the "network". Not a large deal since much of the content is unique to the subsites, but there is also a fair bit of cross traffic between the subsites. Since the function is pretty much a convience to many (cookie storing your password) it really is not a problem. Thanks again,

Well, there is a way to do this, but it's kind of a trick. Check out how to do it with ASP:

I'm sure something like this can be used with php. It's a hack, pure and simple, but it might work for what you need. It's essentially like using an "outside cookie" value.

Best,
