Topic: Xajax refresh only if content is new
I am using xajax to display an image and recall the function periodically to get a new source address from server. The image source is not changing as fast as xajax refresh does. So, same image is refreshing in every refresh cycle.
I would like to know whether there is a way to keep the image without refreshing until image source has a new address in sever side.
Any support is highly appreciated.
