Our subscription service allows website owners to display our pages on their websites. The pages contain industry-specific information that is hard to come by, so we collect and make it available to website owners.
I am noticing a lot of activity and errors coming through one of our feeds. The errors are unusual such as undefined variables, dropped sessions and such. The errors are only happening via this one feed and the owners of the feed are not complaining of seeing any errors. I am suspicious that we have someone out there running code to scrape our screens and pull our data.
My question is two-part:
Is there some way I can tell if its a human or software accessing the site?
Is there a way to prevent this (excluding captcha which would not be practical as we don't form submits and can't ask a user for this every time they view a page).
Thanks for any help!
I am using MS IIs 6, Windows 2003 server, Coldfusion 8
