Interface HTTPHeaders

@Immutable
public interface HTTPHeaders

Represents a group of HTTP headers.

Header name comparison in this class is always case-insensitive, in accordance with RFC 2616.

This class exposes methods to convert to and from different representations such as maps and multimap, for easier access and manipulation – especially when dealing with multiple headers with the same name.
