The verb interfaces now use verb::unknown instead of boost::optional<verb> == boost::none to indicate that the request-method is an unrecognized string. The http::header interface is modified to focus more on the verb enum rather than the string. For recognized verbs, the implementation stores an integer instead of the string. Unknown verbs are still stored as strings. * header::method now returns a verb * header::method_string returns the method text
