no-cache headers for my AJAX requests. A popular trick that I learned from a friend and this discussion thread was to use a dummy parameter that will always different for each AJAX call. For example:
var d = new Date(); var myURL = "http://myserver:myport/myapp/myaction?d="+ d.getDate() + d.getHours() + d.getMinutes() + d.getMilliseconds();
Or you can use a simple counter variable.
