025 * HashMap {@link HeadersMapFactory} which uses a plain {@link java.util.HashMap}.
026 * Important: The map is case sensitive which means headers such as <tt>content-type</tt> and <tt>Content-Type</tt> are
027 * two different keys which can be a problem for some protocols such as HTTP based.
028 * Therefore use this implementation with care.
