HttpResponse.ClearHeaders Method

Clears all headers from the buffer stream.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public void ClearHeaders()

ExceptionCondition
HttpException

Headers are cleared after the HTTP headers have been sent.

The following example calls the ClearHeaders method to ensure that no headers are sent with the current response. This technique can be especially important if the ASP.NET response is generating an image, such as a JPEG file. In this example the ContentType property is set to image/jpeg.

// Clear headers to ensure none
// are sent to the requesting browser
// and set the content type.
Response.ClearHeaders();
Response.ContentType = "image/jpeg";
