Session failure is usually caused by the session lifetime expiration or server shutdown. The solutions: 1. Extend the lifetime of the session; 2. Use persistent storage; 3. Use cookies; 4. Update the session asynchronously; 5. Use session management middleware.

Problem: Today, we encountered a setting timeout problem in our project, and changes to SpringBoot2’s application.properties never took effect. Solution: The server.* properties are used to control the embedded container used by SpringBoot. SpringBoot will create an instance of the servlet container using one of the ServletWebServerFactory instances. These classes use server.* properties to configure the controlled servlet container (tomcat, jetty, etc.). When the application is deployed as a war file to a Tomcat instance, the server.* properties do not apply. They do not apply,

Solution to the cross-domain problem of PHPSession In the development of front-end and back-end separation, cross-domain requests have become the norm. When dealing with cross-domain issues, we usually involve the use and management of sessions. However, due to browser origin policy restrictions, sessions cannot be shared by default across domains. In order to solve this problem, we need to use some techniques and methods to achieve cross-domain sharing of sessions. 1. The most common use of cookies to share sessions across domains

JavaScriptCookies Using JavaScript cookies is the most effective way to remember and track preferences, purchases, commissions and other information. Information needed for a better visitor experience or website statistics. PHPCookieCookies are text files that are stored on client computers and retained for tracking purposes. PHP transparently supports HTTP cookies. How do JavaScript cookies work? Your server sends some data to your visitor's browser in the form of a cookie. Browsers can accept cookies. If present, it will be stored on the visitor's hard drive as a plain text record. Now, when a visitor reaches another page on the site

With the development of the Internet, PHP applications have become more and more common in the field of Internet applications. However, high concurrent access by PHP applications can lead to high CPU usage on the server, thus affecting the performance of the application. In order to optimize the performance of PHP applications, Memcached caching technology has become a good choice. This article will introduce how to use Memcached caching technology to optimize the CPU usage of PHP applications. Introduction to Memcached caching technology Memcached is a

In recent years, WeChat mini programs have become popular all over the world and have become the platform of choice for many enterprises and individual developers. In the development of mini programs, we often encounter session problems, that is, how to save user login status in mini programs. This problem is not unfamiliar to website developers, but it is a little different in small programs. This article will introduce how to use PHP to solve session problems in WeChat mini programs. 1. Overview of the mini program login process The login process of the mini program is similar to the login process of the website and is divided into the following steps:

Optimization of asynchronous communication between PHPSession across domains and AJAX With the development of the Internet, cross-domain access and asynchronous communication have become common requirements in modern web application development. This article will focus on how to use PHPSession to achieve cross-domain access, and provide some optimization methods to improve the asynchronous communication efficiency of AJAX. 1. The problem of cross-domain access In Web development, when the browser initiates an HTTP request from a web page of one domain name, and then returns the response data belonging to another domain name, it will occur.
