Does refering URL always work?

[matrix211v1]

Hello All!

 

I have Apache installed as my web server. On a different server with web page content, like CNN for example, they are going to link to a graphic on my server.  The graphic is actually a passed parameter to a PHP script on my server.

 

My question is this. If someone goes to the CNN page with their browser, it should call the web page of CNN, which in turn will call the PHP located on my machine. Can I record the EXACT url where it was called from OR is it limited to the Host?

 

Another way to look at this is if you went to a person's MySpace page, who had a graphic (linked using the PHP script) that was on my server. Will I be able to go to that individual's MySpace account and see my graphic there OR is it just going to tell me it came from MySpace.

 

Thanks in advance.

It will tell you the full URL

 

e.g. www.cnn.com/newsstory23423.php

 

 

and you can access the referral URL from the HTTP supervariables from php

thats one of the basics in gd

 

google it...

Try

$_SERVER['HTTP_REFERER']

. But as I remember in PHP manual they don't guarantee this will work always.

 

But I think that is what you need.

PHP grabs the referring URL from the HTTP request header.  It is up to the client whether or not they send a referring URL in their request.  Therefore you can't count on it always being there, or if it is there, that it is legitimate.

So if you solved your issue I think it would be nice for all of us if you could use Solved button (according rules of this forum).
