Many sites use something like click.php?url=widgets.com.
All click.php does is look for the URL argument, and then do a redirect to whatever the argument is, in this case, widgets.com. Look at the links in posts here in WebmasterWorld - they do the same thing.
Your log program can then tell you the number of times that each click.php variation was accessed, which gives you the stats you need.
I would suggest for the benefit of your advertisers that you do a 301 redirect in your click.php script rather than a 302.
