    38   * Implements the HTTP GET method.

    40   * The HTTP GET method is defined in section 9.3 of
    41   * <a href="http://www.ietf.org/rfc/rfc2616.txt">RFC2616</a>:
    42   * <blockquote>
    43   * The GET method means retrieve whatever information (in the form of an
    44   * entity) is identified by the Request-URI. If the Request-URI refers
    45   * to a data-producing process, it is the produced data which shall be
    46   * returned as the entity in the response and not the source text of the
    47   * process, unless that text happens to be the output of the process.
    48   * </blockquote>
    49   * </p>
    50   * <p>
    51   * GetMethods will follow redirect requests from the http server by default.
    52   * This behavour can be disabled by calling setFollowRedirects(false).</p>
