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

(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

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

Learning node (2) from 0 to 1 and building an http server During the course of the previous section, we learned about the connection and differences between different module specifications. In this section, we officially started learning about node. First, we started from setting up an http server and running simple programs.

happy, Bo Master Harvest to the first comment, thank you lazy millet serious reading, will continue to work hardrecently, Bo Master learned about the HTTP service build, this time to introduce the construction of HTTP services and some related configurationLab Environment: CentOS6The default HTTP version in CentOS6 is 2.2Installation and startup of

proxy is "equivalent" to a TCP connection established with the server. Of course we have already said that this direct connection is just an illusion. The packet sending and receiving process is as follows: [Client]-http connect a. B. c. d: port-> [proxy]-TCP SYN-> [server][Client] [CLIENT]-ssl client hello-> [proxy]-ssl client hello-> [server] # SSL handshake Package 1[Client] [CLIENT]-ssl client certific
