The process of establishing an HTTP request is actually the process of establishing a socket link,(1) Connect-+ establishes the socket link based on the Domain name address and HTTP default 80 port;(2) Send-and-client sends data in accordance with HTTP protocol format (outputstream.write);(3) Receive-server waits for Inputstream.read to return data(4) Close, client and server di

(1) Basic Concepts Carriers can divide networks based on specific policies based on geography, management scope, and technology. The carrier can regard the subdivided network as composed of different routing domains to provide routing services. The routing domain provides the abstraction of route informa

regulations or rules that must be followed by two computers in a computer communication network. Hypertext Transfer Protocol (HTTP) is a communication protocol, it allows the transfer of Hypertext Markup Language (HTML) documents from the Web server to the client's browser Currently, HTTP/1.1 is used.Web server, browser, Proxy Server When we open the browser, enter the URL in the address bar, and then we

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

What does "HTTP" do with the drip?First, HTTP is a network protocol that is specifically designed to help you transfer Web content. Even if you don't know about this agreement, at least you've heard of it? For example, you visit my blog's homepage, the browser address bar will appear the following URLhttp://program-think.blogspot.com

syntaxThe authorization section is typically the name or IP address of the server, sometimes followed by a colon and a port number. It can also contain user names and passwords that must be exposed to the server. The path section contains the path definition for the hierarchy, in general, separated by/(slash) between the different parts. The query section is typically used to transfer parameters that are required to dynamically query the database on

transaction script is excellent, you still have a few objects tired. However, when the business logic is a bit uncertain, for example, there is a code that decides what operations to execute based on the type of things, you should not create a bunch of if else or switch, let's get an object level to process this. However, when creating a domain model, you must first think about the responsibilities and the owner of all objects. Map to Relational Da

The parameter log2parmrglevel is located in pps, meaning that in the merge mode, the size of the inside of the block Pu can be parallel (parallel) to do the MV operation. For example Log2parmrglevel = 6, then the MV of the 64x64 pu
