 *                  The request is executed on each hosts until one succeeds.
 * @param request   the request to execute
 * @param responseHandler the response handler
 * @param context   the context to use for the execution, or

 *
 * @return  the response object as generated by the response handler.
 * @throws IOException in case of a problem or the connection was aborted
 * @throws ClientProtocolException in case of an http protocol error
