Can anybody help me with a Java script that will replace the [CACHEBUSTER] below with a random number in a html page?

http://adfarm.mediaplex.com/ad/bn/0-0-0-0?mpt=[CACHEBUSTER]

To what end???


javascript runs AFTER the page has been cached by the browser.

You could try something like: ( havent tested )

<script language="javascript" type="text/javascript">
<!--

var nocache = Math.random();
document.write('<a href="http://adfarm.mediaplex.com/ad/bn/0-0-0-0?mpt= ' + nocache + '">Link</a>');


//-->
</script>

its not random, but its unique* per user, and it works for the "**** cached ajax response" and similar issues:

var link = "_ttp://adfarm.mediaplex.com/ad/bn/0-0-0-0?mpt=" + (new Date).getTime();

* - its current time in milliseconds, if you will need more randomness, add Math.random() to that, but in 99.9% cases you wont.
