. The relationship between the HTTP protocol and the TCP/IP protocol(1) HTTP is the application layer protocol, the TCP protocol is the Transport Layer protocol, and the IP Protocol is the network protocol.(2) IP protocol primarily addresses network routing and addressing issues(3) The TCP protocol mainly solves the IP layer protocol, how to reliably transmit the data, that is, the size and sequence of packets received by the receiving end, and the sending side is consistent. The TCP protocol is

The number of IIS or Web connections refers to the access requests that the server can respond to at the same time, and it is easy to understand how many browser windows are allowed to access your site simultaneously, such as: 100 IIS connections can have 100 browser windows connected to the server simultaneously. When a Web page is browsed, the server establishes a connection to the viewer's browser, each

The solution is to modify/etc/mysql/my. cnf and add the following line:Set-variable = max_connections = 500Or add the parameter max_connections = 500 to the startup command.It is to modify the maximum number of connections, and then restart mysql.

Before we explore this issue, let's assume a classic connection model: Client-> Load balancer-> realserver Pool And we assume that there is a load balance using NAT mode, in this mode: 1. The load balancer only leaves the client a public network IP address (VIP); 2. The client sends the request to be the load equalizer end cut, then forwards through the dispatch algorithm to the Realserver pool inside a server; 3. These realserver are in a private network, not externally visible; 4. When t

There is a three-way handshake to open a TCP/IP connection, and a four-way handshake to close it. however, once the connection has been established, if neither side sends any data, then no packets are sent over the connection. TCP is an "idle" protocol,Happy to assume that the connection is active until proven otherwise. TCP was designed this way for resiliency and efficiency. this design enables a graceful recovery from unplugged Network cables and router crashes. e.g ., A client may connect to

Push" technology based on Pure browser is starting to get more attention, Alex Russell (Project Lead of Dojo Toolkit) calls this "server push" technology that is based on HTTP long connections and does not need to install plugins in the browser. There have been some mature Comet applications and various open source frameworks, and some WEB servers such as Jetty are also making a lot of improvements to support a large number of concurrent long
