After studying the design concept of Asp.net, we have an essential understanding of the pipeline of httpapplication. The so-called pipeline is actually a Production Pipeline composed of a series of steps, and httpcontext is the product to be processed on this pipeline. Now, let's take a closer look at this production l

Note: 1 is quasi-parallel, not real parallel.2. The pipeline improves the utilization of components and the average execution speed of commands,Speed of executing a single commandNoImprove. The features of assembly line commands: the commands executed by the assembly line are the same operation commands, and they can be divided into several identical steps. It can be clearly seen that, without using the

IPC inter-process communication + pipeline PipeIPC (Inter-Process Communication ).MPs queues are used to share data between processes. The essence is shared memory, one of the commonly used IPC. Pipelines can be used not only for communication between local processes, but also for cross-network process communication. Like Socket communication, pipelines also encapsulate the underlying network implementation of computers and provide a good API interfac

1. Pipeline commands Pipeline commandThe operator is: "|". It can only process the correct output information sent from the previous command, but cannot directly process the error information. Then, pass it to the next command as the standard input. Management command output description: [Command 1] correct output, as the input of [command 2], and then the output of [command 2] as the input of [c

Pipe is a shared memory area used for inter-process communication. The process for creating an MPS queue is called the MPs Queue Server, and the process connecting to the MPs queue is called the MPs queue client. One process writes information to the pipeline, while the other process reads the information from the pipeline. The anonymous pipeline is a character-b

Request processing PipelineThe request pipeline is a combination of the modules that are used to process HTTP requests, and in ASP., the request pipeline has two core components: a IHttpModule and IHttpHandler . All HTTP requests IHttpHandler are entered, with the IHttpHandler final processing, and IHttpModule through HttpApplication the events in the subscription object, the request can be preprocessed or

commandUse pipelines to connect multiple processes together, allowing each process to collaborate to achieve complex functionality.Pipeline understandingA pipeline is a buffer that is managed by the kernel, which is the equivalent of a small note that we put into memory.One end of the pipeline connects the input of a process, and the other end connects to the input of another process.The pipe does not need

ASP. NET Web API Security pipeline, asp. netapi This article describes the Security pipelines of ASP. NET Web APIs. Here, the security pipeline refers to various components or processes experienced in the request and response process, such as IIS, HttpModule, OWIN, WebAPI, and so on. This pipeline is divided into two phases: one is the verification phase and the

Content pipeline architecture Describes the architecture of the xNa game studio content pipeline build process. The process is designed to be extensible, so that it can easily support new input file formats and new types of conversion. While most users of the content pipeline can ignore its inner workings, if you are a game developer who wants to create a n
