HttpWebRequest.MaximumResponseHeadersLength Property


Gets or sets the maximum allowed length of the response headers.

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

member MaximumResponseHeadersLength : int with get, set

Property Value

Type: System.Int32

The length, in kilobytes (1024 bytes), of the response headers.

Exception Condition

The property is set after the request has already been submitted.


The value is less than 0 and is not equal to -1.

The length of the response header includes the response status line and any extra control characters that are received as part of HTTP protocol. A value of -1 means no limit is imposed on the response headers; a value of 0 means that all requests fail.

If the MaximumResponseHeadersLength property is not explicitly set, it defaults to the value of the DefaultMaximumResponseHeadersLength property.

If the length of the response header received exceeds the value of the MaximumResponseHeadersLength property, the EndGetResponse or GetResponse methods will throw a WebException with the Status property set to MessageLengthLimitExceeded.

The following code example sets the value of this property.
