ASP.NET web service 413 request entity too large error-CodePudding

The

I don't have anything special in API config class.

public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); var appXmlType = config.Formatters.XmlFormatter.SupportedMediaTypes.FirstOrDefault(t => t.MediaType == "application/xml"); config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType); } }

The bindings in my config for this service

<webHttpBinding> <binding name="SecureServerBindingWithUserNameRest" maxReceivedMessageSize="52428800"> <readerQuotas maxArrayLength="10485760" /> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Basic" proxyCredentialType="None" /> </security> </binding> <binding name="webHttpTransportSecurityRest"> <security mode="Transport" /> </binding> </webHttpBinding>

You can try this solution, try to increase the upload size limit. IIS uses uploadReadAheadSize parameter in applicationHost.config and web.config files.

Open IIS Manager

Select the site

Double click "Configuration Editor"

Select system.webServer and then serverRuntime

Modify the uploadReadAheadSize value to 2147483647

Click "Apply"

You might also consider executing a dummy get request just before posting large content. When a https connection is initialized, this first request should not be very large. Once the https connection is initialized proceeding requests are not limitted.
