场景：多租户Orchard 1.9.3部署在单个实例Azure Web App中运行所有设置＆amp;媒体存储在Azure blob存储中。
启用文件系统输出缓存后（所有缓存项都存储在App_Data\OutputCache文件夹中，我看到条目被添加到文件夹中就好了。但是看起来有长URL的项目会抛出错误并导致500的有时这是一个很长的网址，但有时常见的广告系列管理链接（Google Analytics的UTM代码）会导致问题，因为他们使用额外的查询字符串选项制作长网址。如下所示，错误是< strong>无效路径，当它尝试在缓存中查找文件时。
以下是一些错误（请注意错误中的链接现在可用，因为我已禁用缓存并且错误消失了。）
我注意到1.9.x版本中的文件系统输出缓存发生了变化......长网址是个问题吗？
