<PRE>In short: you can't.
Browsers may send origin/referer/.. headers depending on the type of
request, but you can't rely on them to be real or even just there.

><i> Thank you. I couldn't work out if that's the host being called from or the host name in the request. For example, a store called things.com makes a request to my service on widgets.net. I need to see that the request is made FROM things.com for validation purposes. Is it correct that host will provide this?

</I>>>><i> Hi,

</I>>>><i> When receiving a Cowboy request, is there a way to find out which hostname the user made the request from? I'm using CORS in my REST and Bullet app, where each call can be made through a given account. However, I'd like to be able to lock requests for each account to a designated hostname to protect that users account usage.
