[SOLVED] Ajax problem

[scuff]

so I have this code that uses ajax to update every second and because internet caches I need to use urls with random queries on the end like this

       var randomnumber = Math.floor(Math.random()*1000001)
        var file = 'serverTime.php?dummy='+randomnumber; 
        ajaxRequest.open("GET", file, true);
ajaxRequest.send(null);

but the problem is, is that it creates a lot of files in the temporary internet files folder, so if they are on the page for along time it makes a lot of files and takes up room on their hard drive. Is there any way to do this without creating thousands of temporary files?

You could send the correct headers in the PHP file to tell the client to not cache the content.  (Google "PHP don't cache" and something should come up.)

 

 

No guarantees that that will work 100% of the time with all browsers though.

thanks a lot! it seems to be working in ie and i'll test in other browsers later

I'm sure the other browsers will handle it correctly.  IE was the one I was wondering about ;p.  But still, safest to test it.
