我知道我的设置有点疯狂,但不管……

我在Openshift上设置Nginx来缓存从我的家庭网络提供的地图图块(对于地图查看器,你可以猜到目的,:-)),它具有有限的带宽(愚蠢的无线连接！). Openshift为我提供了无限的带宽和1 GB的磁盘,这应该足以缓存地图的流行部分.

但是,地图查看器喜欢这样的请求：

http://localhost/tiles/world/t/-1_0/-27_23.png?1381358434308

这使得Nginx认为该文件不可缓存！我做了一些google搜索,但因为我在阅读和写作的正则表达式太可怕了,我想请求(你)的方式,使Nginx的忽略查询字符串为.png文件,只是服务的版本从缓存中没有请求参数.

以下是服务器配置的相关部分：
