SSO cookies for non-sap Apps

HI,

My understanding is as follows:

Currently SSO is configured between SAP portal and non-sap portals. Once the user is logged-in netweaver portal a logon ticket(MYSAPSSO2 cookie) is created in the browser. In my netweaver portal even non-sap applications are configured. When i click on non-sap apps a logon ticket(JESSIONID) is created.

I have two questions from the above:

1) If there are 50 non-sap apps will there be 50 cookies created ?

2) Can't we use same cookie(MYSAPSSO2) to logon into non-sap apps ?

Please suggest.

Thanks

Mano
