Hi....
I am developing a project using AJAX. It is something called as a virtual whiteboard. Virtual whiteboard is an application in which objects or text which are dragged and dropped on the virtual whiteboard are reflected on the whiteboard of all participating users. The information can be text, standard images like flowchart symbol, basic shapes, mathematical symbols and picture.
I am faced up with two issues in this. I want a method so that the server should send data(here the update of the coordinate positions of the various elements) to the various clients without the client requesting. All I could think of is a timeout functiion in the client side which will keep on checking the server for updates. Is it feasible? Is there an alternate method available?
Should I necessarily use XSLT to dynamically generate div id in the div html tags?
I would be very thank ful for your help. I am unable to proceed.
Kindly do help
