Links are like: ht*p://www.mysite.com/go/?url=description1 which returns a 302.
The issue with the one quoted from the other thread is that it requires JS enabled.
Anyway, as I posted earlier, I'm finding sometimes that where the linked-to page should be in SERPS, my script (go/index.php) replaces it. This is a problem either I or the relevant search engine should be addressing. Who and when though?
