GetAttribute and setattribute are used together, and getparameter is used to obtain parameters such as request.The web is the use of the request/response architecture, and request and response are the corresponding two objects generated on the server side, request can get the parameters and related information that the client passes, and the response is to respond to the client related pages and information.Request.getrequestdispatcher (). Forward (Request.response) This statement means that the

point:(1) Nagle algorithm can avoid network congestion to some extent; disabling the Nagle algorithm avoids delays in successive packets, which is important for writing low-latency network services. Tcp_nodelay option to disable Nagle algorithm. (2) __attribute__ ((deprecated)) indicates that the function is obsolete, eliminated, using such a function will warn you when compiling! AcceptorThe

in front of network programming (1) We learned that if you want to access the resources of other hosts, then you need to know the URL of the resource. So if we know the URL, how do we go toaccess the resources on its host? This articlemainly about the Java language Programming Android network programming of the most basic parent class urlconnectiion, the

In order to facilitate our communication with the server, we need to implement a network communication base class.The implementation code is as follows:Import Java.io.BufferedReader;Import Java.io.BufferedWriter;Import java.io.IOException;Import Java.io.InputStreamReader;Import Java.io.OutputStreamWriter;Import java.net.MalformedURLException;Import Java.net.URL;Import java.net.URLConnection;Import Com.jikexueyuan.secret.Config;Import Android.os.AsyncT

When using FTP software for data transmission, there are times when a disconnection occurs, which may be related to the network environment, the hardware environment, and the software environment.If there are frequent interruptions in FTP management, you can compress the website program files you want to upload into a compressed file, using the software such as FZ to continue the breakpointThere are many reasons to drop packets, such as: Server perfor
