In your MVC sites, you often need to serve up miscellaneous static content, such as http://example.com/About, http://example.com/Contact, etc. Instead of creating controllers for each of these, you can organize them into a single controller like so:
routes.MapRoute(
	"StaticContent",
	"{action}",
	new { controller = "StaticContent" },
	new { action = "About|Contact" } // Add more here
);
Create your StaticContentController with action methods About() and Contact(), and you’re good to go! The important part is the constraint new { action = "About|Contact" } (which is a regular expression) that will prevent any other URLs from inadvertently using this route.
