Hello everyone,
this question is actually about a combination of technologies... javascript,XMLhttprequest object, asp/asp.net, maybe web services...
i want the ability to have a real time conversation with someone on the web. i want to do this by using http request to get data from xml and post data to an asp file or aspx or asmx file... and this file writes the data to that xml file... but the problem is that when i have written data to a xml file then i want to read it with javascript, the httprequest object........ i can do this... but i constantly have to poll the xml for changes..... is it possible to do this without having to constantly poll the xml file ?
for example that when I post data to the asp file that the asp file sends somesort of a warning to all clients that there is new data available in the xml file .........
I hope someone can help,
thx,
Inter
