问题
I have an asp.net site which uses the same database as another JSP site. The JSP site does some reporting and asp site is used for data entry. What I need is once a user is logged in to asp.net site and clicks on one of those common id's, I want to take them to the jsp site to show the report without having them to sign in again. The username and password for the jsp site is exactly the same as asp since they use the same user table. The JSP site is 3-4 years old and I am not at all experienced in it. So if anyone can help me out here.
Here is the Response Header and Request Header for the login into JSP site:
**Response Headers**

Thanks.

When someone clicks on the link for jsp site... I would send user to an intermediare page... Which has a form with user name and password as hidden field. Set the action of the form to jsp's form(which is used for login). And auto submit form using javascript.
