Hi friends,
I develop an web application using JSP/Servlets. Where there are three types of users are there(Admin,Customer,Vendor).
* After they login a new sesion ID is created and when they press Logout it invalidates the sesion. But when i click the back button,it goes to the previous page and can able to use the options available for the user who is already logged out.
* At the same time two users cant able to login the system like Admin and customer. What may be the problem.

Any help would be appreciated

Firstly it looks like you need to add some 'no-cache' code to your secured pages. This prevents them being retained on the client machine and therefore being able to be retrieved without resubmitting the request.

Secondly, this sounds like either a state problem, maybe the servet has instance fields?
I agree. Here's the link:
