404 Invalid SID Value In Strophe While Using Attach()

I attempted to find an answer to my question with the search engine but i was unable to. I'm using strophe.muc.js in my backboen project in order to make it real time website. And

Solution 1:

In case anyone has met the same problem as me, I've done it by adjusting my code above a little bit (changing the place off setting the rid, sid, and jid from join() to $(window).unload().

$(window).unload(function() {
     sessionStorage.setItem("rid",self.connection.rid);
     sessionStorage.setItem("sid",self.connection.sid);
     sessionStorage.setItem("jid",self.connection.jid);
});

No need to increase rid .
