Recently due to the course work, to do an HTTP server, now record the course I do the whole process of the homework. (a) theoretical knowledge HTTP (hypertext Transfer Protocol) is a set of rules for computers to communicate over a network. Computer experts design HTTP to enable HTTP clients (such as Web

these behind-the-scenes jobs work. As a programmer, you only need to ensure that the developed programs can run efficiently. However, during development, you often need to use classes such as HttpContext. At this time, have you ever thought about the composition of these classes and how they are created? You may simply answer: HttpContext represents a context of the current request. But you know IIS, Framework, Asp. net is how to work together to process each

As an Internet developer, the meaning of the HTTP status returned by some servers must be well-understood, and only these status code one by one can be figured out, and all the problems encountered in the work are handled with ease. Well, let's look at the more common HTTP status codes here!2 Opening (successful request) indicates that the status code of the request was successfully processed.200 (success)

what is the HTTP protocol?HTTP is an abbreviation for the Hyper Text Transfer Protocol (Hypertext Transfer Protocol). Its development was the result of collaboration between the World Wide Web Association (Wide) and the Internet Working Group IETF (Internet Engineering Task Force), which eventually released a series of RFC,RFC 1945 defines the http/1.0 version.

This week begins-face-to-face meetings at the IETF in how to approach HTTP 2.0 and improve the Internet. How the industry moves forward together in the next version of Http–how every application and service on the Web Communi Cates Today–can positively impact user experience, operational and environmental costs, and even the battery life of the Devices you carry around.As part of this discussion of

Abstract This memo explains how to usethe upgrade mechanic in HTTP/1.1 Initiate transport layersecurity (TLS) over an existing TCP Connection. This allowsunsecured and secured HTTP traffic to share The same well known port (inthis case, http: at 80 rather Https: at 443). It alsoenables "virtual hosting", so a single

What is cgicgi currently maintained by NCSA, NCSA defines CGI as follows: CGI (Common gateway Interface), Universal Gateway Interface, it is a program that runs on the server such as: HTTP server, provides interface with client HTML page. Web browsing in order to better understand how CGI works, we can click on a link or URL from the Web page: 1. Use your browser to access the URL and connect to the HTTP We

Principle of HTTP escape: using HTTP 0.9 for bypass This is the first article in the HTTP escape series. Most firewalls only block packets that are incorrectly identified by rules. Therefore, data packets that cannot be understood by the firewall can be easily bypassed. The protocols used in this article are old but still use the

1. Long connectionHTTP 1.1 Supports long connection (persistentconnection) and requested pipelining (pipelining) processingHTTP 1.0 Specifies that the browser and the server only maintain a brief connection, each request of the browser needs to establish a TCP connection with the server, the server completes the request processing immediately after disconnecting the TCP connection, the server does not track each customer also does not log past requests.HTTP 1.1 Supports persistent connection per

Through this section of the study, I believe you have a basic understanding of the first structure, and the role of each header field Body HTTP messages are made up of HTTP headers, empty lines, and HTTP message bodies.HTTP message bodies p

1. Status Code Overview The HTTP status code is responsible for the return result of the client HTTP request, the marking of the server-side processing is normal, the notification error, and so on. HTTP status codes, such as 200 OK 3-digit and reason phrases. The first digit in the number specifies the response category, and the latter two bits are n

HTTP packets are text-oriented. Each field in the packet is an ASCII string, and the length of each field is uncertain. HTTP has two types of packets: Request Message and Response Message. HTTP Request Message An HTTP request Message consists of four parts: request line, request header, empty line, and request data. O

Http cache and http Cache I haven't written a blog for a long time. Now I am almost New Year's Eve. Recently, my project is not very busy. I wrote a blog as the first in 2018. I just regained my impulse to write a blog a few years ago after graduation. Http protocol is something that every programmer needs to know, whether it's front-end staff or back-end staff.
