$globals[http_referer]

[jl9148]

i know that $GLOBALS[HTTP_REFERER] means the page you were previously on, but is there another php variable that redirects you to the page previous of the previous page?

for example:
$GLOBALS[HTTP_REFERER] => -1 pages

is there one for -2 pages?

I believe you're referring to $_SERVER['HTTP_REFERER'], but no, there isn't one to retrieve any other previous pages.

In fact, the only way this variable will even be filled with data is if the client's browser/gateway passes this information onto the server. This HTTP header can easily be left blank or even falsified.
