How to pass SSO Ticket in URL

Hi,

My requirements is to access SAP R/3 back-end system from web application by passing Portal SSO ticket.

I am getting SSO Ticket (MYSAPSSO2) from cookies in my JAVA code and want to pass this with request URL to access back-end SAP system.

Can you please help me to explain how can I pass MYSAPSSO2 ticket in the web URL? or any other way I can access SAP backend from external web applications?

Thanks!!
