asp.net - How to use short urls for categories in MVC -

short urls containing product categories like

http://example.com/computers 

should used in asp.net mvc 4 shopping cart. if there no controller, home index method id parameter computers should called.

i tried add id parameter home controller using

public class homecontroller : mycontrollerbase {     public actionresult index(string id)     {         if (!string.isnullorwhitespace(id))         {             return redirecttoaction("browse", "store", new             {                 id = id,             });          }             return view("index", new homeindexviewmodel());     } 

but http://example.com/computers causes 404 error

server error in '/' application.

the resource cannot found.

description: http 404. resource looking (or 1 of dependencies) have been removed, had name changed, or temporarily unavailable. please review following url , make sure spelled correctly.

requested url: /computers

version information: microsoft .net framework version:4.0.30319; asp.net version:4.6.1073.0

how force controller call if there no controller defined after slash in http://example.com/....

mvc default routing used:

public class routeconfig {     public static void registerroutes(routecollection routes)     {         routes.ignoreroute("{resource}.axd/{*pathinfo}");         routes.ignoreroute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" });         routes.maproute(             name: "default",             url: "{controller}/{action}/{id}",             defaults: new { controller = "home", action = "index", id = urlparameter.optional }         );     } } 

it looks mvc ignores routing parameter:

defaults: new { controller = "home", action = "index", id = urlparameter.optional } 

howe fix ?

your problem because aspnet mvc trying find controller name computers, , controller home, can add new route before route name default:

routes.maproute(             name: "computers",             url: "computers",             defaults: new { controller = "home", action = "index", id = urlparameter.optional }         ); 

in above case, creating route match url http://domain.com/computers , route manage homecontroller.

also, according comment, can have route like:

routes.maproute(                 name: "default",                 url: "{id}",                 defaults: new { controller = "home", action = "index", id = urlparameter.optional }             );
