How to solve the problem of session coexistence across domain names under Yii2

The problem was found in the springboot project production session-out timeout. The problem is described below: In the test environment, the session-out was configured by changing the application.yaml. After setting different times to verify that the session-out configuration took effect, the expiration time was directly set to 8 hours for release. Arrived in production environment. However, I received feedback from customers at noon that the project expiration time was set to be short. If no operation is performed for half an hour, the session will expire and require repeated logins. Solve the problem of handling the development environment: the springboot project has built-in Tomcat, so the session-out configured in application.yaml in the project is effective. Production environment: Production environment release is

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.

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

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,

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

Vue is a popular JavaScript framework for building modern web applications. When developing applications using Vue, you often need to interact with different APIs, which are often located on different servers. Due to cross-domain security policy restrictions, when a Vue application is running on one domain name, it cannot communicate directly with the API on another domain name. This article will introduce several methods for making cross-domain requests in Vue. 1. Use a proxy A common cross-domain solution is to use a proxy

When you are using a PHP session (Session), sometimes you will find that the Session can be read normally in one file, but cannot be read in another file. This may confuse you since session data is supposed to be shared across the entire application. This article will explain how to correctly read and write PHP session data in multiple files.
