How to prevent Ajax/javascript result caching in browsers?
The random URL works, but it's kind of a hack. HTTP has solutions built in that should work. Try using the solution indicated here. Basically, set the headers:
"Pragma": "no-cache","Cache-Control": "no-store, no-cache, must-revalidate, post-check=0, pre-check=0","Expires": 0,"Last-Modified": new Date(0), // January 1, 1970"If-Modified-Since": new Date(0)
Add a random query string to the URL you are sending.
E.g. if the Ajax request is sent to "http://www.xyz.com/a"then add a random string at the end: "http://www.xyz.com/a?q=39058459ieutm39"
I've used the jQuery {cache: false} method and it worked like a charm.
The complete code example is like this:
$.ajaxSetup({cache: false});
