That is the usual implementation.  If I have a browser open, I want all 
of the requests made from that browser to go through the same session.  
If I have two browsers, say firefox and chrome, then they will have two 
different sessions.  HTTP does not maintain a connection across mutliple 
requests...with a few exceptions, mostly to streamline the download of 
graphics etc for a single page.  From a WebUI perspective, each JSON 
request would want to use the same session.
