短小请求引起丢失数据

Nginx提前销毁一个请求的可能（至少）：

  • 400 (Bad Request) -- 错误请求
  • 405 (Not Allowed) -- 不允许
  • 408 (Request Timeout) -- 请求超时
  • 414 (Request URI Too Large) -- 请求URI过大
  • 494 (Request Headers Too Large) -- 请求Headers过大
  • 499 (Client Closed Request) -- 客户端关闭请求
  • 500 (Internal Server Error) -- 内部服务错误
  • 501 (Not Implemented) -- 未实现

这意味着正常执行阶段被跳过，如重写或访问阶段。这也意味着，后面的所有阶段，例如 log_by_lua，将无法获得在这个阶段存放的普通信息。

Missing data on short circuited requests

Nginx may terminate a request early with (at least):

  • 400 (Bad Request)
  • 405 (Not Allowed)
  • 408 (Request Timeout)
  • 414 (Request URI Too Large)
  • 494 (Request Headers Too Large)
  • 499 (Client Closed Request)
  • 500 (Internal Server Error)
  • 501 (Not Implemented)

This means that phases that normally run are skipped, such as the rewrite or access phase. This also means that later phases that are run regardless, e.g. log_by_lua, will not have access to information that is normally set in those phases.
