Random number in URL for ad

[flip]

I've done a LOT of searching and have come up with no simple answer for this problem.

Basically I use a seperate app to rotate banners on the top of my site which requires you to add a random number into the URL so that peoples browsers don't cache the image and display the same one.

My question is, in my header code, how would I add a variable to display a random number in the ad url?? I would like to think theres a simple feature already in VB that can do this since it is so robust...

Any ideas?

Here is my code to insert the ad:

<a href='http://ads.blah.com/www/delivery/ck.php?n=a86eebef&amp;cb=INSERT_RANDOM_NUMBER_HERE' target='_blank'><img src='http://ads.blah.com/www/delivery/avw.php?zoneid=1&amp;cb=INSERT_RANDOM_NUMBER_HERE&amp;n=a86eebef' border='0' alt='' /></a>

Try this:

<img src='http://ads.blah.com/www/delivery/avw.php?zoneid=1&amp;cb=[color=red]<if condition="$randomvar = TIMENOW">$randomvar</if>[/color]&amp;n=a86eebef' border='0' alt='' />

That will use the current timestamp as the random number.

You guys are awesome! That works just great...

Thanks!
