A context is a collection of variables and their values.Context is represented in Django as the context class, in the Django.template module. Her constructor has an optional parameter: A dictiona
The code that executes the context is divided into two basic stages to handle:
Go to execution context
Execute code
Changes to variable objects are closely related to these two phases.Note: These 2 stages of processing are general behavior, regardless of the type of context (that is, the performance in the c
In many cases, we need to cache some things in the context, such as the datacontext of LINQ to SQL and the objectcontext of entityframework.
Of course, we should also adapt to non-HTTP requests.
1. commoncontextCommoncontext is mainly used as the base class of the cache context.

Originally HTTP has been designed as a stateless, response-request oriented protocol. However, real world applications often need to being able to persist state information through several logically related requ Est-response exchanges. In order to enable applications to maintain a processing state HttpClient allows HTTP requests to be executed within a par Ticular execution context, referred to as HTTP context
In-depth understanding of javascript prototype and closure (18)-addition: Relationship between context and scope
This series uses a lot of space to explain the context and scope, and some people reflect that these two are one thing. This article uses a small example to illustrate that the scope and context are definitely not the same thing.

The scope is described briefly above, and this article will take a deeper look at the combination of scope and context.As we've described above, in addition to the global scope, each function creates its own scope, which is determined when the function is defined. Instead of being determined when the function is called .Below we will follow the sequence of execution of the program, step by step to add each context. In addition, to the

Analysis of JavaScript scope chain, execution context and closure, analysis of javascript
Closure and scope chain are important concepts in JavaScript. I have read some documents over the past two days and summarized the relevant knowledge points as follows.
JavaScript uses lexical scoping. The scope of variables that function execution depends on is determined by the function definition, rather than the function execution. The following code snippet
