我有一个在 heroku 上运行的 sinatra 应用程序。
我的问题：当我转到本地主机 (http://localhost:5000/) 时，我总是被重定向到生产环境 (https://apps.facebook.com/myapp/)。所以我不能再在本地开发了。
我怀疑我添加的自定义谷歌分析与它有关，见下文（来源：. http://www.savio.no/blogg/a/104/how-to-track-facebook-iframes-with-谷歌分析）。它

var FacebookURL = 'http://www.facebook.com/YourFacebookPage?sk=app_123456789';
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXX-X']);
_gaq.push(['_addIgnoredRef', 'static.ak.facebook.com']);
// If Google Analytics is loaded and this page isn't framed inside our Facebook URL, frame the page.
if (_gaq.push && self.location == top.location) {
// Create a fake URL that we can filter in Google Analytics. This pageview also sends the traffic source data to Google Analytics.
_gaq.push(['_trackPageview','/facebook/campaign-tracking/']);
// Tracking done, let's frame the page
setTimeout(top.location.href = FacebookURL, 200);
} else if (self.location == top.location) {
// If Google Analytics doesn't load within 2 seconds, refresh and frame the page anyway. People dislike waiting. Change the time if you like.
setTimeout(top.location.href = FacebookURL, 2000);
} else {
// The Page is Framed. Let's track it.
_gaq.push(['_trackPageview']);
_gaq.push(['_trackPageLoadTime']);
}
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
所以我删除了它，但 heroku 仍然使用它，请参见下面的网络控制台输出第 3 行。这里发生了什么，它是一个没有被删除的缓存吗？有任何想法吗？
