session problem firebox

[S Bhushan]

I am facing specific problem with firefox browser. I have integrated payment gateway in my website. it is working fine in internet explorer. But I am facing problem with firefox and opera browser. I have some values in session like client id, client name. when I redirect from payment gateway to own site(e.g. thankyou page) I want to access all session variable. It works fine in IE but in other browser session value destroy. it works in local system problem is with online only. Problem occures when I return back from payment gateway to my own web page. e.g.- step 1. payment page(my website page) step 2. paypal (payment gateway) after successfull payment on payment gateway when we click "return to merchant" button.. step 3. thankyou page (my website page) I want to use session variable "I created in payment page(my website page)" I can use these session variable in IE but in case of firefox or opera I cannot get these variables. Thanks Bhushan
