#initialize(args = {}) ⇒ NiceHttp

input: no parameters: By default will access how is setup on defaults one parameter: String "https://www.example.com" "example.com:8999" "localhost:8322" Hash containing these possible keys host -- example.com. (default blank screen) port -- port for the connection. 80 (default) ssl -- true, false (default) headers -- hash with the header key:values debug -- true, false (default) log -- :no, :screen, :file, :fix_file (default). A string with a path can be supplied. If :fix_file: nice_http.log In case :file it will be generated a log file with name: nice_http_YY-mm-dd-HHMMSS.log proxy_host proxy_port

#head(argument) ⇒ Object

Implementation of the http HEAD method. Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content. input: 1 argument Hash containing at least key :path 1 argument String giving the path output: response -> Hash including the symbol keys: :message = plain text response :code = code response (200=ok,500=wrong...) *All keys in response are lowercase
