Someone told me today that a FINDER is a snippet of code that checks remote IPs and
blocks against unwanted hosts.
One way I thought of doing this is from the calling server the link is a form submit
(post method) which contains the HTTP_SERVER_VARS["LOCAL_ADDR"] of the server in the
post info.
My script checks it against a list of allowables and passes or dies.
Is there another way besides submitting a form?
I tried using HTTP_SERVER_VARS["REMOTE_ADDR"] but that returns the client the IP not
the referring IP.
Are they called FINDERS? I couldn't find anything while searching around the net for
info on the idea.
Any comments are welcome
Thanks
