webapi.config

 public static void register(httpconfiguration config)         {          var cors = new enablecorsattribute("*", "*", "*");          config.enablecors(cors);          config.maphttpattributeroutes();          config.filters.add(new unhandledexceptionfilterattribute());          config.bindparameter(typeof(datetime), new datetimemodelbinder()); } 

authentication resource

[datacontract]   public class authentication : baseresource   {     public authentication()     {     }      [datamember(emitdefaultvalue=false)]     public string username { get; set; }      [datamember(emitdefaultvalue = false)]     public string password { get; set; } } 

authentication controller

[routeprefix("sessiontoken")]     public class authenticationcontroller : apicontrollerbase     {         private readonly iauthenticationmanager _authenticationmanager;         authenticationcontroller()         {         }          public authenticationcontroller(iauthenticationmanager authenticationmanager)           : base(authenticationmanager)         {             _authenticationmanager = authenticationmanager;         }          [httppost]         [route("")]         public httpresponsemessage post(authen.authentication auth)         {             auth = _authenticationmanager.createpermanenttoken(auth);             return request.createresponse<authen.authentication>(httpstatuscode.created, auth);         } } 

web.config (iis 8 integrated mode)

<system.webserver>     <validation validateintegratedmodeconfiguration="false" />     <modules runallmanagedmodulesforallrequests="false">         <remove name="webdavmodule" />     </modules>     <handlers>         <remove name="webdav" />         <remove name="extensionlessurlhandler-isapi-4.0_32bit" />         <remove name="extensionlessurlhandler-isapi-4.0_64bit" />         <remove name="extensionlessurlhandler-integrated-4.0" />         <add name="extensionlessurlhandler-isapi-4.0_32bit" path="*." verb="get,head,post,debug,put,delete,patch,options" modules="isapimodule" scriptprocessor="%windir%\microsoft.net\framework\v4.0.30319\aspnet_isapi.dll" precondition="classicmode,runtimeversionv4.0,bitness32" responsebufferlimit="0" />         <add name="extensionlessurlhandler-isapi-4.0_64bit" path="*." verb="get,head,post,debug,put,delete,patch,options" modules="isapimodule" scriptprocessor="%windir%\microsoft.net\framework64\v4.0.30319\aspnet_isapi.dll" precondition="classicmode,runtimeversionv4.0,bitness64" responsebufferlimit="0" />         <add name="extensionlessurlhandler-integrated-4.0" path="*." verb="get,head,post,debug,put,delete,patch,options" type="system.web.handlers.transferrequesthandler" precondition="integratedmode,runtimeversionv4.0" />     </handlers> </system.webserver> 

routeconfig

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

i trying perform post request, request returns 404. have tried configuration changes mentioned in of posts.

http request

url: http://api.x.com/sessiontoken 

request headers

accept: application/json accept-encoding: gzip, deflate accept-language: en-us,en;q=0.8 connection: keep-alive content-length: 0 content-type: application/json host: api.x.com origin: http://x.com referer: http://x.com/ 

similar changes on local iis(7.5 integrated) work without hassle. same change not work on shared hosting environment iis(8) integrated mode.

observed that, if perform publish , map folder iis , request uri.

virtual folder maps published content returns 404 (local iis7.5)

virtual folder maps code folder returns data (local iis7.5)

set idenitiy of application pool localsystem , started work on local installation after publish.
