Hello, CP>I'm seeing a weird thing. Sometimes my script sees nothing in the CP>$ENV{HTTP_REFERER} variable. Im not sure what is causing this. It CP>works some of the time.
You are never guaranteed to receive a Referer header; first of all, it is sent by the client, and the HTTP client involved has no obligation to set it at all on outgoing requests--it's just a convention that most desktop browsers follow. Second, some application level HTTP proxies block outgoing Referer headers for security reasons. Finally, it's possible that a user bookmarked a page or typed in a URL and hence no Referer was involved at all.
