How can I supress "jsessionid=.." in url?

Hello,

Can someone please tell me how to supress the "jsessionid=" parm in the url?

If I run an app on my local engine it displays the "jsessionid=" parm in the url but on the server it does not. I like the clean look of a url without that parm.

Since it doesn't show up on server I'm assuming it's a setting that needs to be changed on my local machine but I don't know where and I haven't been able to find it in documentation.

Thanks in advance for any help.
