Hi,
The reason you loose your sessiondata is simple: The sessionid is stored in
a cookie together with the domain it belongs to.
Every request to a certain domain send along the cookie, and the possible
ppsessid, and so the server can see if it has a session belonging to that
user.
Imagine what happens if this was not implemented like this (as in early
versions of Netscape): You have 2 windows open, one on
www.wehackforfun.com, and one to your companies intranet. If both sites
receive all cookies, the former one can easily 'steal your session' to your
company's intranetsite, simply by reading the name and value of the
cookie...
If you have 2 different domains, they cannot share a session. (Well, they
can, but that is less straightforward.)
Bottomline, don't try to share sessions across different domains.
If this is really a requirement, you can set this up only if you own both
sites, and let them use a common session storageplace (database eg), AND
let both sites explicitely send the sessionid around via GET, because the
cookie will not work.
I am not sure if that is wise, but it can be done.
