Http protocol and http protocol details
HTTP is an object-oriented protocol at the application layer. It is applicable to distributed hypermedia information systems due to its simple and fast method. It proposed in 1990 that, after several years of use and development, it has been continuously improved and expanded. Currently, the sixth version of HTTP/1.0 is use
"Protocol" is an indispensable concept for understanding servers and networks."Agreement (Protocol)" has the meaning of "rules, provisions".In fact, the function of "protocol" is very wide, in the field of communication, "protocol" provides "in the communication, in what circumstances, in what order, what kind of way t

The protocol in iOS is the declaration of a method, stating that no implementation is required, and that the part of the implementation is done by the compliance party.Look at a small example of a protocol: this example is to give two protocols, and then create two types of people to abide by the agreement.Rogue Protocol (ROGUEDELEGATE.H) #import/** Rogue
Recently in the "HTTP diagram" This book, the book mentions the domestic translation of the name of the HTTP protocol, and give some friends to discuss the original link, I looked at a bit of interesting, and I also think that translation for understanding the agreement itself is very important, the collation of some ideas.The full name of HTTP is Hypertext Transfer Protocol, and the main concern is how Tra
Today's Web program development technology is really a contention, ASP, PHP, Jsp,perl, AJAX and so on. Regardless of how web technologies evolve in the future, it is important to understand the basic protocols for communicating between web programs, because it allows us to understand the internal work of Web applications. This article will be a detailed example of the HTTP protocol to explain, more content, I hope you have patience to see. We also hop

"OSI layer Seven Protocol"
Application Layer
An application that communicates with other computers, which is the communication service of the corresponding application. For example, a word processor without a communication function would not be able to execute the code of communication, and the programmer working on the word processing did not care about the 7th layer of the OSI. However, if you add an option to transfer files, the programmer of the
