Varnish IntroductionVarnish is a high-performance and open-source reverse proxy server and HTTP Accelerator, with a new software architecture, and now the hardware system closely, compared with the traditional squid, Varnish with higher performance, faster, more convenient management and many other advantages, Many large websites are beginning to try to replace

By simply using the openvpn proxy, all traffic on the local machine will go through the Remote VPN Server. However, when we roll over the wall, it is generally the traffic webpage, that is, as long as the http traffic goes through the VPN. Openvpn combined with squid's http forward proxy can provide the wall-over function for

fact, there are simpler implementation methods. We only need to define one source and one target, and then allow the source to only access the target.

Configuring squid proxy for http and rsync is too bad. In what time, the CPU is 4, and the memory is only 1.5 gb ddr. Fortunately, there is USB. It's no fun to install gentoo on a virtual machine. The CPU does not support VT-x and is 32-bit. ubuntu running 32-bit virtualbox is almost slow. Scan the IDC network one day and find an available server, Zhiqiang E7520,

Http_port 8080 The Service port of the squid server is configured using the http_port configuration item. The default value is 3128. To facilitate user use, you can change it to 8080 or provide services on multiple ports. Http_port configuration items support providing proxy services on multiple ports Find the following line: Cache_mem 8 MB Modify it: Cache_mem

multiplexing I/O: In order to support a large number of connections, many Web servers use this structure, in the reuse fabric, while monitoring all connection activities, when the connection state changes (with data, or errors), the connection is assigned to the thread processing, after processing is completed, the connection is returned to the list of connections, Threads or processes are not bound on idle connections.Multiplexed multi-threaded

first of all, what is transparent proxy to introduce? transparent proxy means that the client does not need to know the existence of a proxy server, it changes your request fields (messages), and transmits the real IP, more for the NAT forwarding of the router. The principle of transparent
