Global variables - $_SERVER ?

[beagle]

Hi everyone,

I'm new here and need help desperately ... any help/tips/comments will be very much appreciated.

This is the scenario:

www.mymainsite.com/track.php

where "track.php" is a tracking script. I would like to find out if someone linked to me, whether are they linking directly to me or are they using a "header( )" redirect or a "meta refresh".

For example, consider this page:

www.abc.com/widget.php

How may I know if the contents of "widget.php" has this direct link:

1) href=www.mymainsite.com/track.php OR

2) It is a redirect script, e.g.
header("Location: http://www.mymainsite.com/track.php")

Is it possible to find out ? If anyone has any pointers to where to start looking for the information, that will be fine as well.

Thank you very much !

Best regards,
Adrian

? Do you mean you want to know where a hit came from? $_SERVER['HTTP_REFERER'] would your best best - it's sometimes empty, though, both for the obvious reason and because browsers aren't obliged to provide such information.

Taking your post at face value, the solution is to download the entire Internet (source code included) and trawl through it looking for references to your site, parsing it to find which ones are actual links and which ones are just references to the site.

Hi,

No, it's not the HTTP_REFERER - I've those. Let me give you an example:

This page, "widget.html" contains 2 links:

link1:

< a href=http://www.abc.com/track.php>

Logic: Visitor --> abc.com/track.php

link2:

< a href=http://www.redirect.com/go.php >

Logic: Visitor --> redirect.com/go.php --> abc.com/track.php

My script, "track.php" (at abc.com) will have the referer, ie. "widget.html".

Question:

How can my script know which link (link1 or link2) that the visitor came from ?

i.e. how do I tell if a visitor is using a redirection, eg. header( ) OR a direct link (link1) ?

Thanks !

Best regards,
Adrian
