/**
 * SECTION:soup-message
 * @short_description: An HTTP request and response.
 * @see_also: #SoupMessageHeaders
 *
 * A #SoupMessage represents an HTTP message that is being sent or
 * received.
 *
 * You would create a #SoupMessage with soup_message_new() or
 * soup_message_new_from_uri(), set up its
 * fields appropriately, and send it.
 *
 * Note that libsoup's terminology here does not quite match the HTTP
 * specification: in RFC 2616, an "HTTP-message" is
 * <emphasis>either</emphasis> a Request, <emphasis>or</emphasis> a
 * Response. In libsoup, a #SoupMessage combines both the request and
 * the response.
 **/

/**
 * SoupMessage:
 *
 * Represents an HTTP message being sent or received.
 *
 * @status_code will normally be a #SoupStatus value, eg,
 * %SOUP_STATUS_OK, though of course it might actually be an unknown
 * status code. @reason_phrase is the actual text returned from the
 * server, which may or may not correspond to the "standard"
 * description of @status_code. At any rate, it is almost certainly
 * not localized, and not very descriptive even if it is in the user's
 * language; you should not use @reason_phrase in user-visible
 * messages. Rather, you should look at @status_code, and determine an
 * end-user-appropriate message based on that and on what you were
 * trying to do.
