I've noticed these 404 errors in my traffic stats. The reported links are like this: http://www.usbmemorysticks.net/frame.php?back=/?Operation=ItemLookup&ItemId=B000HFCEKW&amazonurl=http%3A%7B%2B%7D%7B%2B%7Dwww.amazon.com%7B%2B%7Dexec%7B%2B%7Dobidos%7B%2B%7Dredirect%3Ftag%3Dusbmemorystic-20%26path%3Dtg%7B%2B%7Dbrowse%7B%2B%7D-%7B%2B%7D468520 http://www.usbmemorysticks.net/frame.php?back=/?Operation=ItemLookup&ItemId=B00008NG70&amazonurl=http%3A%7B%2B%7D%7B%2B%7Dwww.amazon.com%7B%2B%7Dexec%7B%2B%7Dobidos%7B%2B%7Dredirect%3Ftag%3Dusbmemorystic-20%26path%3Dtg%7B%2B%7Dbrowse%7B%2B%7D-%7B%2B%7D468520 http://www.usbmemorysticks.net/frame.php?back=/index.php?Operation=CustomerReviews&ItemId=B0011ZK6ZM&ReviewPage=12&amazonurl=http%3A%7B%2B%7D%7B%2B%7Dwww.amazon.com%7B%2B%7Dexec%7B%2B%7Dobidos%7B%2B%7Dredirect%3Ftag%3Dusbmemorystic-20%26path%3Dtg%7B%2B%7Dbrowse%7B%2B%7D-%7B%2B%7D46852 Code (markup): I have no clue what these page urls are and where they would be generated on my site. I'm noticing that they all say "frame.php?back=" so does this have to do with a user clicking through to amazon and then maybe hitting the back button? Can't actually be because I always have my affiliate links set as "open in new window". I'm also noticing that my affiliate code isn't in these links. So I'm really wondering what they are...anyone have a clue?
I just noticed that these urls are approached only by "Mozilla 5.0". Is this a bot? Or does that mean these 404s only happen to users of that browser?
