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 | |
