Perhaps in the pages which are being linked to, you could add in a
security check that examines CGI.HTTP_REFERER. If the referer is not an
authorised one, you can log this value somewhere and deny access.

Afternoon, all.
Client has a football league/results site, for which he does not charge -
but makes most of his income on this site from ads, both paid and adsense.
Just lately it has been reported that a number of other sites are creating
links to his results pages (some of them) within their own applications
and charging for the information.
I am waiting for him to advise me exactly how he knows this, what the
sites are (and their IP addresses). In the meantime, I agreed to
investigate how this sort of thing might be prevented.
The main site (on its peak day, Monday) is now hitting 400,000 pages (not
hits, pages) on a good day. Not huge, but the advertising revenue on a cpm
basis is significant, and any diminution hits his pocket (and indirectly,
mine).
I thought of creating another table listing IP addresses of such
'thieving' sites, running every page through an IP address query, and
making their users type in some sort of authentication before connecting
to his CF pages. How long they could stand this before complaining to the
thieving admin I don't know - assuming it is possible.
It seems like a bit of overkill, and I think I'm probably missing a trick
somewhere.
Anyone got any other suggestions - Google doesn't give me too many options
(or I'm asking the wrong questions......).
Cheers
Terry
