A proxy server is usually not installed on your computer; it runs on a separate computer on the network, and the network has been configured so that your computer is forced to go through the proxy server.
In order to tell your computer to go through the proxy server, you have to enter proxy settings into your Store Manager for PrestaShop.
HTTP proxy server is a proxy, allowing working on the Internet with HTTP.
It (as well as other proxy servers) can carry out caching of information downloaded from the Internet.
Note: During an HTTP connection, the IP address of the client machine is necessarily transmitted in order to get the information back. This allows a server to identify the source of the web request. Any web resource you access can gather personal information about you through your unique IP address - your ID on the Internet.
