Calling this method is equivalent to calling the Set method on the collection returned by the Headers property.
If the header specified in name does not exist, this method inserts a new header into the Headers property's collection. If name is present in the collection, this method replaces the existing value with value. To add a value to an existing header without replacing the existing value, use the AppendHeader method.
The following code example demonstrates adding a header using this property.
Public Shared Sub SetExpirationDate(ByVal seconds As Long, ByVal response As HttpListenerResponse)
response.AddHeader("Expires", seconds.ToString())
End Sub
public static void SetExpirationDate(long seconds, HttpListenerResponse response)
{
response.AddHeader("Expires", seconds.ToString());
}
