---- Solutions to 302 Hijacking
chadmg - 8:48 pm on Mar 11, 2005 (gmt 0)When someone visits a page on your site, you detect whether the referrer is from an outside website. (Yes, I know that the referrer is not guaranteed correct, but it's all I've got.)
I haven't fallen victim to this scam yet, but I'd rather prevent this than react to it. So I'm enlisting WebmasterWorld's help in coming up with a hopefully only temporary solution. Here's one idea I've had. Maybe we can improve upon it or come up with a better one.
You check this referrer against a list of trusted referrers, whether from a database or text file or other means.
Optional: Check the server headers of the referrer for a 302 redirect.
If the referer is yet untrusted (and a 302), you log the referer and display a meta tag on the page, such as
<META NAME="GOOGLEBOT" CONTENT="NOINDEX">
This way other SE's will still index you.
Then you look through your referrer log on a regular basis to see if you can trust any of the your new referrers
