Change Referral Url

The refer header is controlled and sent by the browser, so in short, no.

Uhm... HTTP headers are very easy to fake.

You can find an example to set the REFERER header in an HTTP request here:
[microsoft.com...]

(less than 10 lines of Perl code)

I know nothing about Pearl...can this be done with PHP or javascript?

tombola, yes it is easy to write an application that fetch a page and will spoof the referer. What you can't do is force the another application (e.g. the browser that the user is using) to report a different referer to what it decides to send as the referer; which is what in my opinion inveni0 is asking for. You cannot do this, not without writing Malware that infects the browser in question.

Let's clarify:

Is there a program that will 'spoof' a referrer. For instance, let's say I refer someone from my page (www.mysite.com/links/link.php?name=109437) to another site (www.yoursite.com). I'd like to spoof my referral url so that, when checking their tracking software, www.yoursite.com will show that my referral came from www.mysite.com.

Is this possible?

No -- you can't change a browser's referer string from your web server.

Like for many "impossible" things, there's an easy way round (I'm sorry, I can only do this in Perl):

1. Transform your home page into an executable program:
www.mysite.com/index.cgi
2. On your link pages, use POST instead of GET to send visitors to index.cgi
For example:

<form method="post" action="http://www.mysite.com/">

<input type="submit" name="submit" value="http://www.otherdomain1.com/"><br>
<input type="submit" name="submit" value="http://www.otherdomain2.com/"><br>
<input type="submit" name="submit" value="http://www.otherdomain3.com/"><br>
<input type="submit" name="submit" value="http://www.otherdomain4.com/"><br>

</form>

3. Create a routine in index.cgi that checks whether a redirect must be executed (if not, display your home page)

When visitors click on a link, they are sent to [mysite.com...] (no need to add index.cgi!)
Depending on the "submit" value, they are immediately redirected to the site in question.
The webmaster of that site will see [mysite.com...] as the referer.

PS. You can use CSS to remove the borders from the input boxes so they look like real links.

That may work!

What I do is this:

Link to a redir-page using a tag (PHP) like this > [mysite.com...]

Then, I have code in the redir.php page that checks for an existent $URL string and then redirects to the url using a meta tag (this makes it look to trackers as if the redir.php page was never even loaded). On the end of [yoursite.com,...] I add?SRC=MySite. This seems to work fine, and is much like your idea.
