1. Go to the above url 2. Click on "map" next to the "A Touch-of-class Florist" listing. 3. The "map" url has two question marks in it, since it's passed through a click-through counter script. The url basically looks like this: http://hostname/script.cgi?args&LOC=http://hostname/targetpage?name=args after clicking on the link, this becomes: http://hostname/script.cgi%3Fargs&LOC=http://hostname/targetpage?args 4. You get a page not found error because of the ? -> %3F encoding. If you click on the "http://gtesupersite.com/touchofclass" link, it works, because this link does not have a second "?" in the url.
