    If the value of 'URL_method' is 'get', the request will consist of the value of 'URL' coming back in
    the initial response.  If value of 'URL_method' is 'post', any additional params coming back in the
    initial response ( in addition to 'URL' ) will be encoded and appended to URL and a post will be performed.
