+..- __url__ , where to save data (ex: /my/awesome/script)
+..- __requestContentType__ ("application/json; charset=utf-8" | "application/x-www-form-urlencoded; charset=UTF-8") default json
+example
+```json
+save : {
+      method: "POST",
+      url: "/save/step1",
+      requestContentType: "application/json; charset=utf-8"
+//      requestContentType: "application/x-www-form-urlencoded; charset=UTF-8"
