This class contains the headers that are part of a WebRequest or WebResponse. Some headers should not be accessed through this collection. Instead, use the corresponding properties of the WebRequest or WebResponse (or the HTTP-specific subclasses). These headers are Accept, Connection, Content-Length, Content-Type, Date, Expect, Host, Range, Referer, Transfer-Encoding, and User-Agent.
