What is Proxy Server

What is Proxy Server?
A proxy server is a machine that sits between the proxy users and the internet servers that they need access to. When a proxy user requests a certain remote resource using a URL, the proxy server receives this request and fetches the resource to fulfill the client’s request. This process enables the proxy server to store the requested content in a cache. Any new request that asks for information already in the cache no longer
needs to be serviced by fetching it from the remote server. Instead, the new request is servi
ced from the cached data. In typical proxy scenarios, the purpose of a proxy server is to fetch the requested resource from the remote server, return it to the requesting user, and cache it in local drives.
In simple words it hides your identity on the internet. A proxy consists of an IP address in xxx.xxx.xxx.xxx format and a port.
Example: 190.139.101.154:8080 Here proxy IP is 190.139.101.154 and proxy port is 8080. To add proxy to your browser use these instructions:
