This interceptor creates the HttpSession if it doesn’t exist, also SessionMap is recreated and put in ServletActionContext.
This is particular useful when using the <@s.token> tag in freemarker templates. The tagdo require that a HttpSession is already created since freemarker commits the response to the client immediately.
There are no parameters for this interceptor.
There are no obvious extensions to the existing interceptor.
