TCP/IP protocol Learning (4) C # Socket-based Web Server --- static resource processing, A Web server is the host of a Web resource. It must process requests from a browser on the user side and specify the corresponding Web resource to be returned to the user. These resources not only include HTML files, JS scripts, and jpg images, it also includes dynamic content generated by software. To meet the above re

Scheme Jump ProtocolOverview: The scheme in Android is an intra-page jump protocol, a very good implementation mechanism, by defining their own scheme protocol, it is very convenient to jump to the various pages in the app,Through the scheme protocol, the server can be customized to tell the app which page to jump to, you can customize the jump page through the n

So Pragma:no-cache and Cache-control:no-cache are used at the same time.use cache directly, do not go to server authenticationPress F5 to refresh the browser and enter the URL in the Address bar and then enter. These two behaviors are not the same.Press F5 to refresh the browser, and the browser will go to the Web server to verify the cache.If you enter a URL in the address bar and then enter, the browser will "directly use a valid cache" without sending an HTTP reques

Step 4: getting started with Protocol Buffers in Java Protocol Buffers (protobuf) is a Google technology used to serialize and deserialize structured data, which is often used for network transmission. This product is actually similar to XML generation and parsing, but protobuf is more efficient than XML, but protobuf generates bytecode, which is less readable th

Java 2 platform version 1.3 is a Java image API (reflection API) adds an extremely practical extension: Dynamic proxy class. A dynamic proxy class is a class that implements a series of interfaces specified during runtime. This proxy can make . In other words, you can directly call any method of any interface on the proxy object-of course, you must first set the necessary type (casting ). Therefore, we can use a dynamic proxy class to connect a group
