      Q&A

      I have a native desktop app as well, how do I link to a custom protocol handler on the desktop?
        IE Only: http://msdn.microsoft.com/en-us/library/ms537512.aspx#Version_Vectors
        All Other Browsers: Use a custom plugin like iTunes does: http://ax.itunes.apple.com/detection/itmsCheck.js
