Question

Alternative Header() command to set Referer in PHP?

Answer 1

+1 A:

The Referer, or generally any request header, is always set by the requesting party. Your server, which is the responding party, cannot force the client (browser) to set any specific header for a request. It's completely up to the browser what headers to send.

The only thing you could do is to download the image via cURL, faking any header you want (because you're the requesting party) and output the image from your server to the client (basically acting as a proxy). It sounds like you're doing something you're really not supposed to though, so I'll leave it up to you to figure that out.

I understand how to fake headers in curl, but again I need to do this client side. I don't want the files, the clients do. So if PHP can not force the headers of the request is there a way to do it in javascript when i make the request to the php file that currently redirects me?EDIT: I apologize if this is OT as javascript is not in the tags.

@ANaNiMuSe You could set request headers using Javascript, yes. You could get the raw image data that way and create an `<img>` element using it. That may or may not be what you want, you won't be able to download just the image, it will always need to be embedded in an HTML page. But you should really read my answer again carefully.

I just tryed this as a fix:die("<html><head><title>redirect</title><meta http-equiv=\"Refresh\" content=\"0; URL=$referringurl\"><head><body onLoad=\"javascript: window.location='$filelocation';\"></body></html>");Not werkin... Can you elaborate on your javascript solution? I know a) its possible to accomplish this b) i'm really close to figuring it out but will either need to bang my head against the wall for more hours or find a magician who has encountered this beast before.Thanks in advance!

@ANaNiMuSe The only way I could think of using Javascript would be an AJAX request and using images with [Data URIs](http://en.wikipedia.org/wiki/Data_URI_scheme). That's only compatible with a limit number of browsers though. I think any attempt through redirects is doomed.
