I have a scenario where I am going to have a div that periodically
updates information from the server (think like a newsfeed or stock
ticker). I am using AJax on the browser side to accomplish this now.
However, I am wondering if it is possible for when the update request
comes in to the server If it is determined that the content hasn’t
changed to send back an “abort update” somehow to the browser that would
cause the div to remain unchanged. I am fairly new to the Prototype
classes in general so I am not even sure where to begin with this.
