God, this saved my butt- I can’t believe there isn’t some mention of this in the PHP online documentation in the section on session variables. Maybe someone has left a comment in there, but it always seems to be a ton of reading to find any pertinent info in the comments on the manual.

Basically had a issue where I use all kinds of session variables for a shopping cart on a site I developed, and when loading the secure pages from a non-www domain to the cart (which uses the www prefix) the session variables weren’t available. Added the line to the .htaccess file and voila! All is happy, no need to modify any php.

thanks so much for a post on what would seem to be a very common problem!

I have 3 sub domains and one main domains

Code I am using is:
session_set_cookie_params(3600,’/',’.cmela.com’);
session_start();

But it’s not working… it works fine on main domains but when i go to sub domain it logs out… can you please suggest me anything??

Thank you

I wouldn’t use the domain switch on shared hosting for security reasons; if you have your own box then that would be acceptable, but it’s a whole can of worms if you ask me.

Hi,
Please make it more clear with example code so that medium level developers can also understand. i think you have good idea. but this post doesnt explain the solution properly. Please make some sample piece of code what to be added in php file as well as in .htaccess so that we can apply with out any doubts.

Thanks in advance.
