Session ID is stored in the memory. when the browser is closed, the ID is automatically deregistered. after the page is requested again, a Session ID is re-registered.
If the client does not disable the Cookie, the Cookie plays the role of storing the Session ID and Session lifetime when the Session is started.
Let's manually set the Session lifetime:
The code is as follows:

::someclass syntax;*In addition, there are two more special namespaces:*Global Namespaces and anonymous namespaces. The global namespace is the default namespace, and identifiers declared outside of the namespace that are declared are in a global namespace, and anonymous namespaces are namespaces that do not have names that require the declaration to be displayed. The statement reads as follows:*namespace{*various declarations within the anonymous namespace (function declaration, class declarati

In an application, to work with the listener object that attaches the handler to the event source, the handler appended to the event source may not be damaged. This situation may cause memory leakage. Windows Presentation Foundation (WPF) introduces a design pattern that can be used to solve this problem. This pattern provides a dedicated manager class for a specific event and implements interfaces for the event listener. This design pattern is called the "weak event pattern ".
Why implement the
Effects : effects/effects. particle system: particle systems. Can be used to create smoke, airflow, flames, ripples and other effects.After the Unity3d 3.5 release, the new Shuriken particle system was exited:Effects after adding a component:The Open Editor button opens the Particle editor, which allows you to edit complex particle effects. Because the shuriken particle system is a modular management method, it is possible to add modules dynamically: 1. Initialize the module:
, to ensure the security session. Typically, if the session's lifetime is not set, the session ID is stored in memory, the ID is automatically logged off after the browser is closed, and the session ID is re-register after the page is again requested.
If the client does not disable the cookie, the cookie plays the role of storing the session ID and duration of the sessions at the time of the start.

How does the Session determine the client user? It is determined by the session ID, what is the session ID, is the file name of the session file, session ID is randomly generated, so to ensure uniqueness and randomness, to ensure that the session security. In general, if the lifetime of the session is not set, the session ID is stored in memory, the ID is automatically logged off after the browser is closed
server side, and every variable we register is the key to the array, not the same as using the array.
What if I want to log out of the system? The Session can be destroyed.
Copy CodeThe code is as follows:
Session_Start ();
This method destroys a variable that was originally registered
unset ($_session["admin"]);
This method is to destroy the entire Session file

It is through the session ID to judge, what is the session ID, that is the file name of the session file, session ID is randomly generated, so can ensure uniqueness and randomness, to ensure the security session.

In the local variable declaration before the static local variable->, storage mode changed, local variable is dynamic storage, static local variable is static storage mode, that is, c
simultaneous forward and back search methods. The algorithm first makes a brief forward search, and selects an optimal forward candidate node. Then go back to the search. At this point, the back-search is not toward the start node, but toward the newly-obtained forward candidate node. A back search will also select the best Forward Search node. Then next, run the forward search, from the current forward candidate node to the back candidate node. This process will be repeated until two of the se

C #ClassStatic MemberThe life cycle of a variable is the time when it is created, and when it is destroyed. The "Lifetime" of a declared element is the time period that the element is available for use. A variable is a unique element with a lifetime. Therefore, the compiler treats process parameters and function return values as special cases of variables. The
