Web Api Service HTTP status code 405 on method POST

GET works fine.
But in Chrome with POST method I have:
Failed to load resource: the server responded with a status of 405 (Method Not Allowed).
Failed to load http://localhost:49834/api/Rest/: Response for preflight has invalid HTTP status code 405.
In InterntExplorer I have: SCRIPT7002: XMLHttpRequest: Network error 0x80070005, Access denied.
Controller:
[EnableCors("*", "*", "*")]
public class RestController : ApiController
{
// POST: api/Rest
[HttpPost]
public void Post([FromBody]Request Request)
{
if (ModelState.IsValid)
{
db.Requests.Add(Request);
db.SaveChanges();
}
}
}

);
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;

AJAX POST:
var url = "http://localhost:49834/";
$.ajax({
type: "POST",
url: url + "api/Rest/",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify(submitData),
success: function (data) {
},
error: function (err) {
console.log(err);
alert(err.status + " - " + err.statusText);
}
})
I use IIS Express: applicationHost.config file in %userprofile%\documents\IISExpress\config folder => ExtensionlessUrl-Integrated-4.0 handler is configured like this verb="GET,HEAD,POST,DEBUG,PUT,DELETE"
GET works fine:
$.getJSON(url + "api/Rest").done(function (data) {
var mass = new Array();
$(data).each(function (index, e) {
ReqArray.push(e);
})
vm.requests(ReqArray);
});

There was some problem with my ajax, like this it works good:
var url = "http://localhost:49834/";
$.ajax({
type: "POST",
url: url + "api/Rest",
dataType: "json",
data: submitData,
success: function (data) {
},
error: function (err) {
console.log(err);
alert(err.status + " - " + err.statusText);
}
})

Response GZIP Compression not working .net

I need to compress json response, I have tried IIS dynamic compression and used below code to compress but compression is not working it always Content-Type:application/json; charset=utf-8, Gzip headers are properly send to server. I have tried the code below.There is nothing in failed request tracing. Please suggest a solution.
class CompressFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpRequestBase request = filterContext.HttpContext.Request;
string acceptEncoding = request.Headers["Accept-Encoding"];
if (string.IsNullOrEmpty(acceptEncoding)) return;
acceptEncoding = acceptEncoding.ToUpperInvariant();
HttpResponseBase response = filterContext.HttpContext.Response;
if (acceptEncoding.Contains("GZIP"))
{
response.AppendHeader("Content-encoding", "gzip");
response.Filter = new GZipStream(response.Filter, CompressionMode.Compress,true);
}
else if (acceptEncoding.Contains("DEFLATE"))
{
response.AppendHeader("Content-encoding", "deflate");
response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
}
}
}
I have this settings in web.config file

Updating a config file in c#

I am creating an update to my companies system that will be running on several clients and I have two config files, the old config file and the newer version.
Is there any way that I can compare the both files and check the differences to add to the older file what I have new in the first one?
Keep in mind that the files may have different info and the only thing that I need to add/change is the keys. For example, if a key is different change the older to that new "version", if a key doesn’t exist in the older files add it.
they keys will have the exact same name but may have different values. Plus there could be a new key that doesnt exist in the older file and I need to add it
I will leave an example of the files for you to see,
Any help would be appreciated.

Error 500 instead of 404

I have an asp.net MVC 5 project and I'm trying to throw a 404 error instead of 500.
The errors are
A public action method 'something' was not found on controller
'ProjetX.Controllers.HomeController'
and
The controller for path '/something' was not found or does not implement
IController
I understand why it's an error 500 but I would like to throw a 404. It would be better for SEO.
I can't figure out how to
Here's my code
My ExceptionHandler class for elmah
public class HandleCustomError : HandleErrorAttribute
{
public override void OnException(ExceptionContext filterContext)
{
//If the exeption is already handled we do nothing
if (filterContext.ExceptionHandled)
{
return;
}
else
{
//Log the exception with Elmah
Log(filterContext);
Type exceptionType = filterContext.Exception.GetType();
//If the exception is while an ajax call
if (exceptionType == typeof(ExceptionForAjax))
{
filterContext.HttpContext.Response.Clear();
filterContext.HttpContext.Response.ContentEncoding = Encoding.UTF8;
filterContext.HttpContext.Response.HeaderEncoding = Encoding.UTF8;
filterContext.HttpContext.Response.TrySkipIisCustomErrors = true;
filterContext.HttpContext.Response.StatusCode = 500;
filterContext.HttpContext.Response.StatusDescription = filterContext.Exception.Message;
}
else
{
base.OnException(filterContext);
}
}
//Make sure that we mark the exception as handled
filterContext.ExceptionHandled = true;
}
private void Log(ExceptionContext context)
{
// Retrieve the current HttpContext instance for this request.
HttpContext httpContext = context.HttpContext.ApplicationInstance.Context;
if (httpContext == null)
{
return;
}
// Wrap the exception in an HttpUnhandledException so that ELMAH can capture the original error page.
Exception exceptionToRaise = new HttpUnhandledException(message: null, innerException: context.Exception);
// Send the exception to ELMAH (for logging, mailing, filtering, etc.).
ErrorSignal signal = ErrorSignal.FromContext(httpContext);
signal.Raise(exceptionToRaise, httpContext);
}
}
How I add the custom errors
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleCustomError());
}
The routes config
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute("Robots.txt",
"robots.txt",
new { controller = "robot", action = "index" });
routes.MapRoute(
name: "Localization",
url: "{lang}/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
constraints: new { lang = #"^[a-zA-Z]{2}$" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"NotFound",
"{*url}",
new { controller = "Error", action = "Error404" }
);
routes.MapMvcAttributeRoutes();

I wanted to handle the error in the HandleCustomError class but the problem is that it goes straight to my Error500 action in the error controller.
What's weird is that the error is still logged in elmah.
It doesn't hit any breakpoint inside the HandleCustomError class, how can the error be logged?
Thank you

Here's the final code that works

constraints: new { lang = #"^[a-zA-Z]{2}$", controller = GetAllControllersAsRegex(), action = GetAllActionsAsRegex }
);
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new { controller = GetAllControllersAsRegex(), action = GetAllActionsAsRegex() }
);
routes.MapRoute(
"NotFound",
"{*url}",
new { controller = "Error", action = "Error404" }
);
routes.MapMvcAttributeRoutes();
}
private static string GetAllControllersAsRegex()
{
var controllers = typeof(MvcApplication).Assembly.GetTypes()
.Where(t => t.IsSubclassOf(typeof(Controller)));
var controllerNames = controllers
.Select(c => c.Name.Replace("Controller", ""));
return string.Format("({0})", string.Join("|", controllerNames));
}
private static string GetAllActionsAsRegex()
{
Assembly asm = Assembly.GetExecutingAssembly();
var actions = asm.GetTypes()
.Where(type => typeof(Controller).IsAssignableFrom(type)) //filter controllers
.SelectMany(type => type.GetMethods())

What is the URL that is not working?
What I see is you've corrected the URL from .html to .aspx and it works.
