First, the HTTP protocol principle is introduced:HTTP protocol, full name hypertext Transfer Protocol, Chinese name Hypertext Transfer ProtocolOne of the important applications of HTTP is the WWW servicewww, full name World Wide Web, often referred to as the Web, the Chinese translation of "www"The default port for the WWW Service Application of the HTTP protocol

In-depth analysis of ASP. NET Core pipelines (1): pipelines are used to process HTTP requests and core analysis The reason why ASP. NET Core is called a Web development platform is that it has a highly scalable request processing pipeline. We can customize this pipeline to meet HTTP processing needs in various scenarios. Many features of ASP. NET Core application

1. Introduction to HTTPThe HTTP protocol (hypertext Transfer Protocol, Hypertext Transfer Protocol) is the transfer protocol used to transfer the text from the WWW server to the local browser. It can make the browser more efficient and reduce the network transmission. It not only ensures that the computer transmits hypertext documents correctly and quickly, but also determines which part of the document is

eventually translates into an HTTP response to the client. The message processing pipeline for ASP. NET core is very simple from the point of view of design, but it is relatively difficult to understand from the point of view of concrete implementation, in order to let readers have a deep understanding of this chapter, we start from the simple part.first, speaking from Hello worldTo enable readers to understand the message processing pipeline of ASP.

(message) is composed of a string, in order to distinguish the end of the request header and the beginning of the request body, with a blank line to represent, encountered a blank row, it is the end of the header, the beginning of the request body. Request Body The request body is the real content that the client submits to the server, such as the user name and password to be used when the user logs in, such as the data uploaded by the file, such as the form information submitted when registeri

to the web server, and then the server returns an http response message to us. The above process is called a transaction, which is a complete response process consisting of an http request command and an http response command. This explanation may not be intuitive enough. We can use the telnet tool (for telnet linux users, you can install it through yum or apt-

1. Why is it Fiddler? There are many packet capture tools, ranging from the most commonly used Web debugging tool firebug to the powerful Generic Packet capture tool Wireshark. Why use Fiddler? The reason is as follows: A. Although firebug can capture packets, it is not powerful enough to analyze the details of HTTP requests. The ability to simulate HTTP reque

Regardless of the future development of Web technology, it is important to understand the basic protocols for communication between Web applications because they allow us to understand the internal work of Web applications.

1. Use Telnet to test HTTP protocol in command line windowHTTP messages are made up of plain ASCII text. The message includes the message header and the data body part. Message headers in units of behavior, each line with CRLF (carriage return and newline) end, after the end of the message header, add an additional CRLF, after the content is the data body part. We can test the
