asp.net mvc 4 - AuthorizeRoles=admin how redirect to index when is false. -

in mvc 4 application simplemembershipprovider. i'm decorating controller attribute [authorize(roles = "admin")].

when roles false i'm redirecting user login page. how can change redirect index page?

you can use custom authorize attribute overriding authorizeattribute as

 [customauthattribute(roles = "admin")] 

code:

using system; using system.web.http; using system.net.http;  public class customauthattribute : authorizeattribute {     public override void onauthorization(system.web.http.controllers.httpactioncontext actioncontext)     {            /* if authorization condition fails */            if(!condition)            {               handleunauthorizedrequest(actioncontext);            }         }      protected override void handleunauthorizedrequest(system.web.http.controllers.httpactioncontext actioncontext)     {          filtercontext.result = new redirecttorouteresult(                         new routevaluedictionary                          {                             { "action", "/*actionname*/" },                             { "controller", "/*controllername*/" }                         });    } }
