For example, it can cache it for future use, filter it to remove unwanted content, or require authentication before the client can see it.
The proxy server can make changes to the response.The destination server processes the request and responds to the proxy server.If it doesn’t, the proxy server may show the client an error message or redirect it to another server.If it does, the proxy server forwards the request to the destination server on the client’s behalf.The proxy server checks whether the client’s request follows predefined rules.
Instead of directly contacting the destination server, the request goes to the proxy server first.The client (your device or web browser) requests web content or service from a destination server.Internet traffic flows through the proxy server on its way to the requested address, and the request then comes back through that same proxy server before you receive the requested data. It acts on the client’s or web server’s behalf to receive and forward requests. The word “proxy” means “to act on behalf of another,” and that is precisely what a proxy server does.
