I think as an intellectual challenge it would be fun to try to thwart the screen scraper, but how much does the upgrade cost?
I don't really personally care or want to know what you charge for the upgrade, but think of it in terms of, "We charge $xx.xx for the upgrade, the fix is going to take me x hours to do and they might find a way around it once I'm done. Is it worth my time to make this change" If you still want to do it, I would recommend adding a hidden div with a big ole chunk of random chars in it. It won't show up to the user, but the scraper will choke on it. =] On 7/18/07, Robertson-Ravo, Neil (RX) <[EMAIL PROTECTED]> wrote: > You charge people to export content from a web app?!? > > It would seem these users are wise enough to realise that no matter what > approach you take, they will get the content from the page. > > Print Screen, CTRL-V etc etc etc. > > > > > > > > > > > > > > > > "This e-mail is from Reed Exhibitions (Gateway House, 28 The Quadrant, > Richmond, Surrey, TW9 1DN, United Kingdom), a division of Reed Business, > Registered in England, Number 678540.
