This article introduces the knowledge of "there are three ways to maintain http proxy server". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

There are three ways to maintain http proxy servers: one is to maintain at the network layer, which is equivalent to using gateways, such as web proxy servers and Socks proxy servers; the other is to maintain at the IP layer, based on data file sharing, based on http proxy functions; and finally, based on the method of changing the system flow.

The agent operation first searches in the agent cache file area, and if the data information exists and is reasonable, it takes the data information out of the cache file area; if not, it connects to the remote target server to obtain the data information.

Regardless of whether the proxy server reads data from the cache file area or from the Internet remote control server, it will apply the port number 80 according to the HTTP protocol to return the information content to the requestor. In the HTTP communication chain, some forwarding proxy servers usually exist between the mobile client and the overall target server, and display the forwarding browsing of the overall target resources.

An HTTP request will be shared by several proxy servers, and the following server is called the upstream and downstream server of the front server. According to its application method and effect, the proxy server is divided into directional proxy server, reverse proxy server and fully transparent proxy server. The proxy ip specifies the detailed address of the proxy ip set by the mobile client.

Each request from the user is immediately sent to the proxy server, and the proxy ip requests the overall target resource. For example, if the LAN devices in the server firewall want to browse the Internet, or to browse some blocked foreign websites, they must use the forward proxy ip. The reverse proxy ip is set on the server, so the mobile client does not need to make all the settings. The reverse proxy ip accepts the connection request on the Internet, then sends the request to the server on the intranet and returns the results obtained from the internal server to the mobile client.

In this case, the proxy server is mainly open to the outside world as a real server. The fully transparent proxy ip is set only on the gateway. The data information report of the customer browsing the Internet must go through the gateway. If you set up a proxy ip on the gateway, the proxy ip is obviously a completely transparent proxy ip to the customer. A fully transparent proxy ip can be used as a unique condition for forward proxy ip.
