Regarding ASP.NET routing in WebForm & Asterisk sign

I saw people use asterisk sign at the time of routing in webform. i just do not understand the importance of Asterisk sign like below one

routes.MapPageRoute(
  "View Category",               // Route name
  "Categories/{*CategoryName}",  // Route URL
  "~/CategoryProducts.aspx"      // Web page to handle route
);

what is the meaning of asterisk sign and also tell me what kind of situation i should use asterisk sign like above.

"Categories/{*CategoryName}"

it would be better if anyone come with small sample code of using Asterisk sign just to show the importance & use of asterisk sign in real life apps.
