i'm writing a button exchange script and wants to know if the user is submitting a button from a server that allows direct link. is there a way to test that with php? thanks
What is it exactly that you are trying to do. And what do you mean by direct link? Connection by socket, URL, What?
servers that use .htaccess to disallow posting of images from them on other sites.
if someone submit a url say from geocities.com is there a way to tell that geocities.com uses above?
