Note Submitter: farzad dot private at gmail dot com ---- hi there! As a complete newb I fail to understand how I can redirect a page depending on the device the user uses to access my page. The scenario is as follows: I link to a specific php-page (via QR-Code). This page should determine which resolution (and/or user-agent) the users' device has and present him with the right version of a video-file (i.e. different resolution files of the .mp4 or .m4v type). So the user should receive an HD-M4V-version if he is using a tablet like an iPad but a very low .mp4-resolution if he's using an old nokia-phone. aaron's note from december 2004 was a little help but I am too unexperienced to convert this into something that suits my needs....
