我主持一个Ajax网站（AngularJS），它的资产/部分驻留在我的静态资产服务器上运行nginx后面haproxy。
我的设置如下所示：
Web -> Haproxy -> App (custom) and Static (nginx) servers 现在，不时加载特定资产（HTML部分），或者在一次或多次浏览器刷新后才开始加载（Chrome的networking工具显示“未完成”）。
我不知道这是什么原因，因为assets / partials都在同一个文件夹中，而其他的只是加载好。
这里有2个configuration，也许你可以发现一些可疑的东西？
我怎样才能有效地debugging这些问题？
haproxy.cfg.j2 🙁这是一个Jinja2模板，所以不要被模板语法混淆）
