Hi,

Lets say I have a page that loads and says "You came from XYZ". XYZ being the referer we just came from.

I want to blank out the referer variable when my page loads. When my page loads it should say "You came from <blank>"

What i'm trying to achieve is to stop all javascripts running on my page from getting my page referer.

Thanks

Hey,

in PHP you can modify the referer in the $_SERVER variable (if at all, read below):
$_SERVER['HTTP_REFERER']

Statement from the PHP documentation:
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

But I'm not sure about the javascript thing, because the javascript will run on the clients machine, thus in the browser and therefore it might be that the referer is not editable for the javascript part because the php stuff runs all on the server. This depends on how the javascript uses the referer.

You can't do that with Javascript or PHP.

Those headers are set by the client (browser) and recived by the server (webserver).

If you control those Javascript applications, why not just edit them to remove any reference to the referrer?
