Thanks.
Every time the user request the resource,the browser sends the smsession to the webagent, but if you look in the Brower via fiddler/httpfox there will be many smessions accumulated during that user session.If again a new resource is requested by user, which smsssion the browser gonna send? Ideally browser should send the latest smsession but however there are many smsessions in browser, how does browser knows which one had to send?
