What is the little knowledge about the application layer protocol HTTP in linux? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Transport layer protocols use TCP by default

A little knowledge:

1. The forward server requires the client to set the address of the proxy server itself. Each request from the client will be sent directly to the proxy server, and the target resource will be requested by the proxy server (the LAN machine commonly used in the firewall will access the Internet or use the forward direction)

two。 The reverse proxy is set on the server side. The client does not need to make any settings.

Principle: use a proxy server to receive the connection request on the Internet, then forward the request to the server on the internal network, and return the results obtained from the internal server to the client. (at this point, it is like a real server, and different proxy servers can be set up in different regions.)

3. The difference between the two lies in the logical location of the server on the HTTP protocol communication chain.

4. Transparent proxies can only be set on the gateway, and all datagrams accessing the Internety must pass through the gateway.

5. Features: proxy servers generally have caching capabilities

6.linux service is a script (/ usr/sbin/service) that starts, stops, and so on many server programs (such as httpd,vsftod,sshd,mysqld) under the / etc/init.d/ directory.
