HttpResponse.SubStatusCode Property

Definition

Gets or sets a value qualifying the status code of the response.

public:
 property int SubStatusCode { int get(); void set(int value); };
public int SubStatusCode { get; set; }
member this.SubStatusCode : int with get, set
Public Property SubStatusCode As Integer

Property Value

An integer value that represents the IIS 7.0 sub status code.

Exceptions

The operation requires the integrated pipeline mode in IIS 7.0 and at least the .NET Framework version 3.0.

The status code is set after all HTTP headers have been sent.

Examples

The following example sets the SubStatusCode property in an event handler for the HttpApplication instance of the PostAuthenticateRequest event. Put the code file in the App_Code folder of your Web application and configure the Web.config file to register the module.

End Namespace

Remarks

The SubStatusCode property is only supported with the integrated pipeline mode in IIS 7.0 and at least the .NET Framework version 3.0. When you set the SubStatusCode property, the status is logged on IIS 7.0 if failed-request tracing is configured. Independent of whether tracing is configured, the code is never sent as part of the final response to the request. For more information, see Troubleshooting Failed Requests Using Failed Request Tracing in IIS 7.0.
