1. The relationship between the HTTP protocol and the TCP/IP protocolLong connections and short connections to HTTP are essentially TCP long connections and short connections. HTTP belongs to the Application layer protocol, which uses the TCP protocol at the Transport Layer and IP protocol at the network layer. The IP

First of all, here is a brief reference to the HTTP protocol, the HTTP protocol is located at the application level to the object of the protocol, the WWW is now using the http/1.1 version, about http/1.0 is also today to say the content.HTTP1.1 bit HTTP1.0, the biggest difference is the increased support for persistent connections.In http/1.0, a short connection is used by default . That is, the browser and server each HTTP operation, will establish a connection, the end of the task is disconne
Five features of the 1.HTTP protocol1) Support client/server mode2) Simple and fast3) Flexible4) No connectionEach connection processes only one request, and the server finishes processing the customer's request and is disconnected after being answered by the customer.5) No StatusThe protocol does not log server client status.2. Two ways to keep the HTTP connection state1) CookiesWhen accessing a unified Web site, information can be written to cookies to facilitate the extraction of information

Analysis of persistent connections and short connectionsA persistent connection means that multiple data packets can be sent continuously over a TCP connection. If no data packet is sent during TCP connection persistence, both parties need to send a detection packet to maintain this connection, generally, you need to maintain it online. A short connection is a TCP connection established when both parties have data interaction. After the data is sent,

What is a long connection
HTTP1.1 Specifies that long connections are maintained by default (HTTP persistent connection, also translated as persistent), data transfer is done to keep the TCP connection continuously open (no RST packet, no four handshake), waiting for the same domain name to continue to use this channel to transfer data The opposite is a short connection.

Long connections and short connectionsThe so-called long connection, refers to a TCP connection can be continuously sent multiple packets, during the TCP connection remains, if no packet sent, need to send a detection packet to maintain this connection, usually need to do their own online maintenance.Short connection refers to the communication between the two parties have data interaction, the establishment of a TCP connection, after the data is sent
