Denying everyone access to a folder, except an iPhone app
<p>I am working on the website for a company which develops iPhone apps.  One of our apps needs to regularly access a folder on our server (hosted by HawkHost) to update information, and I've figured out how to do that.</p>

<p>What I would like to do is somehow set the permissions for the folder so that only this app can access it and every copy of the app can access it, but all other requests get denied.</p>
