HttpResponseHeaderCollection.TryAppendWithoutValidation | tryAppendWithoutValidation method

Try to append the specified item to the HttpResponseHeaderCollection without validation.

Syntax


var boolean = httpResponseHeaderCollection.tryAppendWithoutValidation(name, value);

Parameters

name

Type: String [JavaScript] | System.String [.NET] | Platform::String [C++]

The name of the item to append.

value

Type: String [JavaScript] | System.String [.NET] | Platform::String [C++]

The value of the item to append.

Return value

Type: Boolean [JavaScript] | System.Boolean [.NET] | Platform::Boolean [C++]

true if the item was appended; otherwise false.

Remarks

The TryAppendWithoutValidation method is available when you need to work with an HTTP header on an HTTP response that doesn't have a strongly-typed class for the HTTP header. If there is a strongly-typed implementation of the HTTP header, then the methods and properties on the strongly-typed class should be used instead of the TryAppendWithoutValidation method.
