/* this demonstrates the buffer_get_token_sa_pred interface;
 * ishttp is the predicate that determines when buffer_get_token_sa_pred
 * stops reading.  It is supposed to return 0 if the token is not
 * complete and 1 if it is.  It can also return -1 to indicate an error,
 * for example you could enforce a timeout here or limit the token size. */
