 OK, I've been having this problem for quite some time but never until
now I really needed a solution. I have never thought of a work around,
so I really need your help. Sorry if this has been mentioned already.
You can point me to the post and I'll gladly read. I googled this a
lot but, first, most people have tutorials for sharing sessions in
subdomains, and, second, I have no clue what keywords to use.

I am currently developing two web sites in my localhost. The first one
is http://localhost/pageone and the other http://localhost/pagetwo. I
have a login script for each. The login script can either be session
based (for temporary logins) or cookie based (for long term logins).

When I login in one site, I create two session variables named user
and key which store a user name and a random 128 characters string.
The key is stored in the database and changes upon each login (a
little security). After successfully logging in in pageone using
sessions, I noticed that in pagetwo I am also logged in. So I added a
session variable "domain" which I check on both pages to see if the
session information is for the right page. Although this works, I
found that now I can only be logged in in one page at a time. I am
assuming that sessions are shared.

Cookies can be set using the domain to avoid this. Is there anything
similar with sessions? Is there a work around? I'm also assuming that
this will not be the case if I buy a hosting and create different
domains for each web page. Is this true?

Thank you in advance.
Panagiotis.

Sessions are shared between all hosted sites unless you change it but it
shouldn't be an issue. Your problem is with cookies. It's pointless to
specify a *domain* in setcookie() because both sites are in the same
domain (localhost). What you need to specify is a *path*.

Same applies to session_set_cookie_params().

Uhm, sorry, indeed, I was already using path in setting the cookie, so
logging in with cookie works correctly. My problem is with sessions.
Because I want a user to be able to login for the current browsing
session. I now have a session_name before session_start with different
name and looks like it's working. I haven't really tested it a lot.

Incorrect. Cookies, which are used to manage sessions, are domain
specific. A browser will not send a cookie to another domain,
irregardless of the host.

In this case both are on "localhost", so the domain is the same.

I've found, from JavaScript, might be the same with PHP, that using
'localhost' works on some browser and not on other, but using
'127.0.0.1' works with all browsers available on Mac OS X.

Even some browser allows cookies when using 'file:///path/to/some.html'
but not all.

Is that right ?
