An HTTP proxy acts as an intermediary between a client and a server, intercepting HTTP requests and responses. When a client sends an HTTP request to a server, the request first goes to the proxy server. The proxy server then sends the request to the appropriate server on behalf of the client.
The server sends its response to the proxy server, which then sends it back to the client. In this way, the client does not communicate directly with the server, but rather goes through the proxy server.
HTTP proxies can provide several benefits, such as improving performance by caching frequently accessed resources, enhancing security by providing an additional layer of protection, and enabling anonymous browsing by masking the client’s IP address.
