Has anyone other than OP actually seen this in the wild? None of the systems I know about on Comcast here in Chicago have had HTTP manipulated at all today. Maybe they're not doing it here because the 250GB bandwidth cap is "temporarily suspended"?
This is the real question. We can laugh all we want to a out their crappy code, but what I want to know is where this code is actually in the wild. If I see this coming down my Comcast connection, I'm likely to cancel my service that day.
If you search for the GIUD that's part of one of the URL's in the code, you can find other places online including someones "Top 404 pages" log. While not widespread (yet), it is indeed happening. This post was from last year, but this month Comcast bumped me up to 100Mbps so I will be purposefully reaching my 300GB limit to test if it's still in production.
