How to adress server node in the url on WAS 620

Hi,

we are running one SAP WAS 620 instance with two server nodes. How can I adress an application on a specific server node?

We tried the following and each try in a new browser session:

https://<host>/irj/servlet/prt/portal/prtroot/com.sap.portal.navigation.portallauncher.default?sapj2ee_*=1451355111

In the http watch I could examine that the cookie sapj2ee_* is always different from the entered one. I'm not on the node where i wanted to be.

Do you have any idea how to solve my problem?

Thanks and regards

Marcus
