Here is the deal. I have created some HTML/Javacript dashboards that will be displayed on big screen displays. The displays are powered by thin clients running WinXP and Firefox 4. There will also be a desktop version as well. I would like to use one url (dashboard.php) and then redirect to the appropriate page. I need to be able to differentiate between the big screen displays and someone using Firefox from the desktop. My thought was to permanently change the UserAgent string on the big screen deployments and use browser sniffing to determine which version to forward the user too. The problem is, it appears that FF4 has removed the ability to change the UA string permanently. Anyone have any ideas on how I could do this or an idea on how I can otherwise differentiate between big screens and a desktop user.

    What about using the IP address of the computers displaying on the big screens? Especially if the big displays are on an internal network, assign them a static IP address and use that to identify the computers. Other than that, just pass a get string saying ?view=bigDisplay or similar. You can simply put in your code

    $bigDisplay = (isset($_GET['view'])&&$_GET['view']=='bigDisplay');

    then you would have a boolean of whether to display the bigDisplay code.

    Edit:
    also, just googled and found this: http://support.mozilla.com/en-US/questions/806795
