  * @param {string} url specifies URL for a request in the standard URI form (e.g. 'http://example.com/path')
  * @param {function} callback specifies callback function in format  `function (err_message, code, body, headers)` that is called on HTTP request completion. if this parameter is missing, the function performs "pseudo-synchronous" call (see [Synchronous and Asynchronous API overview](/doc/developers/sync_async.html#API-example-http-module)

+ * @param {table} headers optional headers in form `[name='value']` or `[name=['value1', 'value2']]` to duplicate a header with multiple values
  * @param {string} mime_type MIME type of the HTTP content (for example, `text/html`)
