caching - Google Ajax feed cache -


i getting pinterest board feed via ajax call. changes on wall not visible in result. have searched solution around caching. seem have problem implementing it.

//url feed var url = 'http://pinterest.com/' + this.options.username + '/feed.rss?nocache=' + (new date).gettime();  ///google service var api = "http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&q=" + encodeuricomponent(this.url) + "&num=" + this.options.limit + "&output=json_xml&callback=?";

this trows error:

uncaught typeerror: cannot read property 'feed' of null  {"responsedata": null, "responsedetails": "feed not loaded.", "responsestatus": 400}

when leave out '?nocache='+(new date).gettime(). cached feed loaded.
