or you just have something like


and all your sites use that to authenticate the user. In your php login
script you can just see which site they came back from and then on a
successful login you just redirect them back to that one. You wouldn't
need to use cookies. You could make your own session ID. I thik owning
say subdomain.mydomain.com and having it point to
www.asite.com/mydomain/subdomain doesn't look as good. The PHP needed to
do something like this would be fairly simple too.

Subject: Re: [PHP] Multiple Domains in cookie?


I have been trying to play with my cookies for a while now for this same

And to no avail..

It seems due to the structure of them and as long as the client
sticks to the specifications you can only access a cookie belonging to
same host..

For example, I am starting up a large "network" site base but I wanted
the sites even though they have their own unique domain to be able to
have a
global member login system.. Catch is.. The only way for them to be able
login to one site and then be able to freely go to another completely
site also on our network they would still be logged in and hence they
this main ONE account that allows them access  to all our network

So I studied the workings behind Terra Lycos and found their trick quite
easily.. Since they have basically this same concept they too had to
find a

And their's is very close to mine :) I had thought.. since it's HOST
specific. Not the full domain.. that means that cookies only
between: aaa.com and bbb.com..

But not: one.aaa.com or two.aaa.com

Therefore to create ONE cookie you set it's host for aaa.com and that
all your other site domains can be redirectors to the subdomain..

Ie.. if you have aaa.com as your main site and bbb.com and ccc.com just
those other two point to: bbb.aaa.com and ccc.aaa.com  respectively..

Don't think it's "unpro" because that's exactly what Terra Lycos does..

For eg.. Checkout www.webmonkey.com (I'm sure many of you already know
you soon see you'll be transported to: www.hotwired.lycos.com/webmonkey

This is because not only is webmonkey part of Terra lycos.. It's also

Then I thought.. No way.. that can't be their trick surely??

Yep.. Checkout all their other sites..

More examples: www.angelfire.com goes to angelfire.lycos.com and
goes to tripod.lycos.com

it seems this is the idea.. that way.. if they login.. just set some
(perhaps the SESSID so you can easily jsut reload the session on the
sites) on for example lycos.com as the domain and then all the
can also use this freely..

Use your domains as redirectors and you get a sweet system.. :)
