nodejs session management

Typically, session management is used to uniquely identify each user session by storing it in the user's Web browser as a cookie through the server. If the browser does not support cookies, or if the browser is set to not accept cookies, we can use URL rewriting to implement session

the same Web site again, the cookie information is sent back to the server, allowing the server to restore the user's last access status. The fundamental purpose of using cookies is to implement data transfer between different pages during user access to resolve HTTP stateless issues. Cookie technology can enhance the service function of the website, bring convenience to the user. However, there are many limitations and deficiencies in cookies, the concept of

For the management of some session programs in the Python framework, the python framework A SECRET_KEY must be configured for all python web frameworks, such as Django, Bottle, and Flask. We usually recommend random values in this document, but it is hard to find that he has any text instructions, this is because it is easy to be cracked (local attacks or text reading are more vulnerable to attacks in web a

cookie| Browser If the browser does not support cookies, or if the browser is set to not accept cookies, we can use URL rewriting to implement session management. Essentially URL overrides are by adding parameters to the URL connection and including the session ID as a value in the connection. However, for this to take effect, you need to add a

In the various session management scheme, the ThreadLocal mode has been used extensively. ThreadLocal isA more specific thread-binding mechanism in Java. Data that is accessed through threadlocal is always associated with the current thread,In other words, the JVM binds a private local instance access space for each thread that is running, which is often used for multithreaded environmentsThe present concur

(For an introduction to load balancing, see the MSDN article ' ASP and Web session Management '). For true load balancing, whenever a user who resides on a server clicks on a connection, it changes the state of the s

The network traffic of full-node replication increases with the increase in the number of nodes, it is because of this factor that can not build

In project development, session is used in multiple places when using the SSH framework integration. In the use of the session maintenance, there are several views: 1.getCurrentSession (); Gets the session in the current conversation, which is managed by the container itself, and spring can broker the transaction. 2.this.getsession (); To obtain or create a Hiber
