[Nginx] 4xx and 5xx retain custom HeadersProblem If the status code returned by the request is 404 or 50x, the custom header is still returned. Analysis and Solution The add_header section in the nginx document contains the following sentence: Adds the specified field to a response header provided that the response code equals 200,201,204,206,301,302,303,304, or 307. A value can contain variables. That is to say, add_header generally does not apply to 4xx and 5xx responses. However, you can

This article describes how to use the Lua script in nginx. The third-party module LUA-nginx-module is used to call the Lua script in nginx. A Configuration example is provided.Lua is a language similar to Javascript. ngix_lua also uses asynchronous single-thread, and its syntax is even simpler than Js. According to previous evaluations, the performance of ngix_lua is almost node. JS.Nginx features1. Popular High-Performance HTTP servers2. event-driven (asynchronous) Architecture3. A small amount

implemented the idea of maintaining the same type definition for relational databases and redis BY USING THE ORM and deserialization methods, and the cached data is quasi-real-time, if the requirements are completely consistent, the version queried from the relational database should be provided. In addition, to get rid of the direct dependency on redis, you can use openresty to achieve transparent access to resources. This is not the focus of this a

Greenev is a Python Network Service framework based on the Greenlet, event-driven, non-blocking socket model, which makes it possible to write synchronous code without the benefit of asynchronous execution.This project was inspired by Gevent, Openresty, Alilua, Skynet, Clowwindy/ssloop, and expressed gratitude here. Reactor mode uses IO multiplexing mechanism based on Epoll, Kqueue, poll, select Completion of scheduling of Upper Greenlet

. If you do not store the database, where should it be stored? 2. The client obtains the token certainly to encrypt the storage, sends the token to decrypt again. Is it stored in a database or a configuration file?
