This article mainly introduces the differences between redis and session, the article is very detailed, has a certain reference value, interested friends must read it!

Redis is an open source log, Key-Value database written in ANSI C language, which supports network, memory-based and persistence. Session is called "session control" in computers, especially in network applications; Session objects store properties and configuration information required for a particular user session.

The difference between redis and session

Native session is more reliable in server-side storage and can be stored in files, databases, and memory.

Use Session to maintain the process of user login transition:

When the user logs in, the login form submitted by the user is put into request

The server side verifies the user name and password

After passing, the user information is stored in Redis, and the key in the database is session_id.

The set-cookie field in the response returned by the server contains the session_id. After receiving it, the client stores its value in the browser.

The request of the operation after the client contains the session_id. After receiving it, the server extracts the session and gets the session in the Redis to complete the business operation.

To use Redis to realize the sharing and storage of session, we must ensure that session_id will not be easily obtained and cracked, set a reasonable failure time, and verify users again for sensitive operations.

These are all the contents of the difference between redis and session. Thank you for reading! Hope to share the content to help you, more related knowledge, welcome to follow the industry information channel!
