This article mainly introduces the implementation code for determining the network type and connection status through JS. For more information, see the complicated mobile network environment in China, the developer wants to know the user's current networking method, and then gives the user a request result that conforms to the current network environment. W3C provides a method to obtain the current network status navigator. connection; according to t

optimization, the timeout setting and management logic of the socket, the size of the cache, and so on.For example, in order to prolong the battery life, chrome on the mobile side tends to delay closing idle sockets (lazy closing of idle sockets), usually to reduce the use of the signal (radio) and close the old one when opening a new socket. Also, because pre-rendering (pre-rendering, described later) uses a certain amount of network and processing resources, it is usually used only on WiFi.Th

Not long ago I installed ubuntu12.04 and found that linux is still very good. I plan to take a look at it for a while. However, I found a difficult problem, that is, the problem of networking. I spent most of my time in school. the network in the school is wireless network. th

Study a lot of ways of networking, even the tcp/ip,shock,http of the relationship is clear, and finally figure out how to use GET or post in unity to communicate, or a little excited, but do not rule out a better way, heard unity can write their own shock. I have not done any research here, it is to use Unity's own WWW class to achieve.This is a relatively simple way, just pass the URL, there are many ways to further data transmission, and so on.I pac

12th. Getting Started with Java networking programming Java provides three main types of network functionality:(1) URL and urlconnection: The most advanced of the three categories, through the URL network resource expression, you can easily determine the location of the data on the network. Using the representation and establishment of the URL, the Java program can read directly into the data placed on the network, or transfer its own data to the

Traditional switches and routers can not meet the needs of users, intelligence has become a trend in all walks of life, networking equipment, in this increasingly networked world, people constantly in new and different ways to use the communication between people and equipment. Some types of communication are already familiar, such as IP voice (VoIP), digital images, multicast, video-on-demand, peer-to-peer file sharing, remote video conferencing, and

they visit a website for the second time. In social networks, users are more sensitive to advertising and even more irritable. This may be because, compared to the traditional site, users of social networking sites have a sense of belonging to the site. Users view social networking sites as a place to get personal information and interact with friends, so not only are they dissatisfied with the ads that ap

page to the browser, possibly including a user-logged in form, but sending an error page to MIDP is meaningless and should send a 404 or 401 error directly, This allows the MIDP application to directly read the response code of the HTTP header to get the error message without continuing to read the corresponding content.5. Because the computing power of the server far exceeds the mobile client, the task of sending different responses for different client versions should be done on the server si

Networking in Java programming includes the ability to locate and identify resources and communicate over TCP and UDP connections. First, you need to identify a resource with a name like www.ibm.com, then open the connection to that resource, and finally send the packet between yourself and the other end of the connection. Other tasks may be included for security reasons, but the whole process is the same. For the Java platform, the classes that suppo
