Hello Folks. Hope everyone is enjoying their time off in the holidays. For the rest of us addicts (I would say most of us), here is a question. I am developing a module that relies on storing something in the session. It works fine on my test machine. When I copied the module to the customer's test machine, I found that sessions behave very strangely. Instead of reusing the session id that was assigned on the last access, it is creating a new session every time the same person from the same browser and same IP address accesses the site. The result is the module does not work, since a new session is assigned, and the old one is not reused, and the stored values are not visible. Looking at session.inc, I found that the function sess_read() is the one responsible for this. It is passed a $key parameter, which I assume is assigned by PHP, and hence is not a Drupal assigned value. I checked the session settings parameters in php.ini on the customer's machine, and found them to be normal. What can be the cause for this?
