Mono provides the necessary software to develop and run .NET client and server applications on Linux , Solaris, Mac OS X, Windows, and Unix….
Mod_Mono that comes with the cPanel/WHM control panel only supports ASP .NET. If you need support for Classic ASP, then your choices are few, invest in a Windows server, or Sun Java System ASP 4.0 (For more info, go to: http://www.sun.com/software/chilisoft/)
The Mod_Mono Plugin is deprecated in the cPanel and should not be used.
We suggest you install Mod_Mono via EasyApache either from the WHM >> Apache Update, or by running the following command at the prompt :
/scripts/easyapache
Installing this version of Mod_Mono is more up-to-date and fully supported, whereas the plugin is not.
