The http::message distribution contains classes useful for representing the messages passed in http style communication. these are classes representing requests, responses and the headers contained within them.

the http::headers class encapsulates http-style message headers. the headers consist of attribute-value pairs also called fields, which may be repeated, and which are printed in a particular order. the field names are cases insensitive.

instances of this class are usually created as member variables of the http::request and http::response classes, internal to the library.
