public String getRawAuthority ()

Returns the raw authority component of this URI.

The authority component of a URI, if defined, only contains the commercial-at character ( '@') and characters in the unreserved, punct, escaped, and other categories. If the authority is server-based then it is further constrained to have valid user-information, host, and port components.

Returns:  The raw authority component of this URI, or null if the authority is undefined
