Help!
Here's the scenario:
I'm hosting and serving display ads. These consist of some media creatives and some javascript files to assemble and display the ad. The files are hosted on a CDN.
We did a small test run with 1 ad over the weekend. It burned about 10,000 impressions. When reviewing my CDN logs, I notice that one single IP, was requesting a single media file, on average about 2-3 times per second to the tune of over 1.6 million hits on the file. All in within a 24 hour period!
Now this is a big problem because I'm charged for bandwidth, and currently we've transferred over a TB for no apparent reason.
Why is this happening?? What can I do to prevent anything from accessing files directly like this? They should only be accessed when the javascript calls them into an ad placement.
