asp.net web api - Opening Default document on IIS -

i've deployed asp.net web api website on same folder consume it.

when type url on browser such http://domain.com/ returns 404, if type http://domain.com/index.html works!

i wanna know if there's way configure on web api route, define default route it, redirecting http://domain.com/index.html when type http://domain.com/

i've tried ti put on web.config without success:

<defaultdocument enabled="true">   <files>     <add value="/index.html" />   </files> </defaultdocument> 

also, set iis accept index.html default document. no success =/

any ideas?

i'm not sure if best way achieve this, edited routeconfig.cs such this:

public class routeconfig {     public static void registerroutes(routecollection routes)     {         routes.ignoreroute("{resource}.axd/{*pathinfo}");          routes.maproute(             name: "default",             url: "index.html"         );     } } 

now can http://domain.com works perfectly!

i'd love if have best way achieve this!
