What is really a Proxy Server?
A proxy server can be an intermediary from a user's device as well as the internet. Instead of directly connecting to a website, your request undergoes the proxy, which then fetches the data on your behalf. This process helps mask your real IP address and adds a layer of security.
Example: If you're in the US but wish to access UK-only content, a UK-based proxy will make it look like you’re browsing in the UK.
How Does a Proxy Server Work?
Here’s a straightforward breakdown of how a proxy server operates:
1️.User sends a request → You enter a website URL inside your browser.
2️.Request travels to the proxy → The proxy server receives the request.
3️.Proxy processes the request → It changes your IP address and forwards the request to the destination server.
4️.Website responds for the proxy → The site sends data back on the proxy.
5️.Proxy forwards the data to you → You receive the webpage while remaining anonymous.
Key Benefit: The website never sees your real IP address, only the proxy’s IP.
