I use a cookie to help with a few small features outside of the forum and it always worked like a charm.  I haven't seem the same system option for a site cookie here in 4 unless its tucked aways somewhere.  Anyone know if it is still there or a way to activate it?

This shouldn't be needed, and has moved to a power setting via constants.php if needed for SSO etc.

If you need to set a cookie domain in IPS4, add this to your constants.php (where x=cookiedomain)

define( 'COOKIE_DOMAIN', 'x' );

 

This is indeed necessary sometimes. I have several apps in different subdomains and I need the cookie to be only "domain.com" instead of "www.domain.com" because if not, the sessions wouldn't work in the rest of the subdomains. This way I can create some kind of SSO using IPS members.

It would be nice to have the constants.php file with some reference to all available variables.

Regards.

As a makeshift reference I usually open up init.php and that has a nice-ish list of these sorts of settings that is fairly easy to understand/guess.
