php find page redirected from

[tr8er8]

hey, i have no clue how to start this one. i need to know how to find the url of the page that i redirected to. what i want, is have a page, and if you dont have enough permissions to view the page, you get redirected to a different page that displays what the error is. the page is going to display different errors for each situation. so im going to do something like:

function redirectedFrom($url) {
//code
}
if(redirectedFrom($url) == $url2) {
echo "error message1";
}

or something similar, you get the point.

It's like anything else though with a stateless protocol like HTTP, you have to "carry" the value along one way or another. Each request is a brand new request so to retain the state of the last conversation you must pass values through cookies, the GET query, sessions, etc.

Which method did you employ?
