Code run on different browser.

Hi, Can anyone tell me if a project runs on a browser and the URL is copied and run on different browser then if it will work correctly or not.
I am facing a problem. If i run my code on Chrome or IE7 or Mozilla,it works perfectly but when i run the code on Chrome and copy the url on IE7 then it shows the error page that i have made that shows that some error has happend.
can anybody explain me whats the problem. I have used the session and some security things too. Could that create some problem?

I have got the solution of my problem. there were some components which were declared static which were creating problem.
