Reference: whether http://ixdba.blog.51cto.com/2895551/708021 varnish can run stably and quickly depends heavily on Linux optimization and varnish parameter settings. After varnish installation configuration is complete, the varnish server

Linux kernel socket optimizerVi/etc/sysctl.confNet.core.netdev_max_backlog = 30000 The maximum number of packets that are allowed to be sent to the queue when the rate at which each network interface receives packets is faster than the rate at which

Agent ImplementationThe agent is typically located between the client and the server. It accepts requests from the client, may modify the request, and then sends the request to the server. The results are then retrieved from the server, and the

A TCP/IP and socket we need to have a certain understanding of the network transmission, especially the TCP/IP protocol and socket.Socket is a method of interprocess communication, which is based on the upper interface of network transport

One, by listening to TCP port communicationPhp-fpm.d/www.conf; The address onwhichTo accept FastCGI requests.; Valid syntaxes is:; 'Ip.add.re.ss:port'-To listen in a TCP socket to a specific IPv4 address on; a specific port;; '[ip:6:addr:ess]:p

On the other side of the client, we will analyze the establishment process of tcpclientsock.Class tcpclientsock: Public basesock { PRIVATE: Sockaddr_in serversockaddr; Protected: Char * prebuffer; Int prebuffersize; Mutable int prereceivedlength;

As a TCP Service Program At the same time, there may be a large number of clients connected, and we hope to remember each socket separately Who has the data to read and put it in a request queue -- these tasks are completed by one thread and

/** Tcpclient. c*/# Include # Include # Include # Include # Include # Include # Include # Include # Include # Define servport 1888# Define maxdatasize 30 Int main (INT argc, char * argv []){Int sockfd, sendbytes;Char Buf [maxdatasize];Struct hostent

The server and client directly using socket are similar to the program. In actual use, it is often "dropped", but the program does not know, and many solutions have been found, I used it all at the end. Here is a summary. 1: set its avalie active

The client uses the iPhone application, and the screen is relatively simple. Click the send button to send some strings to the server. Click the receive button to read some strings from the server and display them on the screen.   The UI section of

When writing a TCP program, for the service side, accept successfully return, it must mean that a client has successfully established a TCP connection? For clients, does the successful return of connect necessarily mean that they have successfully

Socket communication is essential for network communication programs. Therefore, we need a set of established and simple communication procedures. As follows: public class PublicSocket {public const string DOWNLOAD_STATUS_WAIT = "1"; public const

"Learning Notes" Qtcpsever is used for listening, qtcpsocket for connecting clients and server. Client Connection server is very simple, connecttohost (qhostaddress ("IP", 666), the completion of IP and port can, after the successful connection, and

Since select, poll, and AIO are all written, then write it all. #include #include #include #include int main (int argc, char *argv[]){int LISTENFD, CONNFD;struct sockaddr_in serveraddr;Char buff[20];if ((LISTENFD = socket (af_inet, sock_stream, 0))

The code under Windows is as follows Server.cpp #include #include #define IP "127.0.0.1" #define PORT 8888 #pragma comment (Lib, "Ws2_32.lib") using namespace std; char* GetTime (); int main () {wsadata wsadata; WORD Ret; if (Ret =

For the socket does not understand can be viewed: C language through the socket programming TCP communication, Linux socket programming/socket detailed First look at the program renderings Tip If the server, directly through CTRL + Z shutdown, so
