must specifically configure the forwarding agent to access other sites, such as configuring the proxy server address and port number in the browser.A typical application of a forwarding proxy is to provide access to an external Internet network for internal clients behind the firewall , such as campus network users visiting foreign websites through proxies, Company intranet users through the company's unif

After Apache is started properly, you can configure it.
Next, modify the Apache configuration file to support the HTTP Proxy server function. Open in a text editorhttpd.confFile. The file is located in the conf directory of the Apache installation directory. If you do not change the installation path when installing ApacheC:\Program Files\Apache Group\Apac

Configuring the forward proxy is simple. You only need to add the vhost configured by Apache to the
conclusion is that the forward proxy is a server between the client and the original server (Origin server), in order to get the content from the original server, the client sends a request to the agent and specifies the target (the original server), then the agent forwards the request to the original server and returns the obtained content to the client. The client must make some special settings to use the forward
The usual proxy server, which is the forward proxy, is used only for proxy connection requests from the internal network to the Internet, and the client must specify a proxy server and send HTTP requests that would otherwise be sent directly to the Web server to the proxy se

This timeout can be increased by proxy_read_timeout instructions. Alternatively, the proxy server can be configured to periodically send a

Customer-side ssh connection managementThe ssh command can be executed at the end. When the command execution is complete, ssh is disconnected.This feature allows you to call a python script at the end of an ssh command, call a python program, and execute the sleep operation. When the python program exits, the ssh connection is disconnected.

Welcome to Criticize(1) Forward proxyI'm too lazy to draw my own notes.The simple point to the proxy is that when user a accesses server B, it connects to Proxy server Z and accesses B through Z.(The goagent used when turning over the wall is actually the forward agent.)
