very high, use flash socket to simulate websocket is not necessary, in similar to the IE platform, rather than directly using the flash version of theHttps://github.com/yangboz/as3MQTT/tree/master/MQTTClient_AS3What to do if the WebSocket browser is not supportedNot all browsers support websocket, especially the IE6/IE7/IE8/IE9 that hinder historical development

there is no special convention between the client and the server, the extended data length is always 0, and any extension must specify the length of the extended data, or how the length is calculated, and how to determine the correct handshake when shaking the handshake. If there is extended data, the extended data is included within the length of the load data. Application Data:y Bits, arbitrary application data, after the extended data, the length of the applied data = the length of the load

, xhr are constrained by domains, and WebSocket allows cross-domain communication. Ajax is a clever thing to do without designing the way to use it. WebSocket is created for the specified target and is used for two-way push messages.WebSocket reduces latency because once the websocket connection is established, the server can send messages as they become availabl

Socket,websocket,http,tcp and so on we have heard the ears have a cocoon, but use the time to review it. When the university studied the Network foundation, the teacher said that the network is divided into physical layer, data link layer, network layer, transport layer, Session layer, prese

To achieve the goal of this article, it is necessary to directly realize the function of chatting, and, on the basis of the chat function, and then realize the function of the cache chat record. The first step: the principle of chat implementation first, we need to clarify our needs. Usually, the chat on the Web page is the form of the chat room, so, this example also has a chat space concept, as long as in this space, you can chat together. Secondly,

http://alchemywebsockets.net/when I think about WebSocket library, this is amazing. Yes, that's true. 　　It can be lined up behind Fleck, it's very easy to use, easy to install (NuGet packages available), and the documentation contains good examples. It contains both the server and the client, and it also has the Scalability 1 2 3 4 5 6 7 8 9 Ten All in all, the static void Main (string[] args) {//Gen Build a new server-accept port and IP range,//set

WebSocket is a mechanism for efficient two-way communication between the server and the client. Can solve the data real-time requirements of high-quality applications, such as: online chat, online education, stocks or positioning.A: WebSocket produce background:To address this real-time problem, there are several alternatives:1. PollingConcept: The client sends a request to the server through a certain inte

/websocket. The example in Go Web programming is used x/net/websocket as a development package, and it seems to be more official and formal. In fact, according to the feedback I received on the Internet, it is not so. x/net/websocketseemingly Bug more, and more unstable, problem solving is not timely. By contrast, gorilla/web
