A proxy server is a server that responds to queries on another party's behalf. Web proxies frequently employ proxy servers. A client computer using a web proxy server navigates to a website and sends the request to the proxy server. After that, the proxy server retrieves the website on the client's behalf and sends the material back to the client.

Web proxy servers are frequently employed to keep private network computers isolated from the internet while maintaining web access.

From a security perspective, proxy servers can offer a wide range of advantages. This includes doing malware checks on all downloaded files. offering user-level access control, barring specific websites, and logging all web surfing behavior.

Some proxy servers permit caching of web responses. This occurs when a web page or image is kept locally by the proxy server for a certain amount of time. Up until the cached file is regarded to have expired, all further requests for the same page will result in the local cached file being returned. The machines using the proxy server's network bandwidth may utilize much less as a result. Additionally, it improves online browsing efficiency.

Reverse Proxy Servers

A reverse proxy server is a proxy that resides between a web server and the internet as opposed to between client computers and the internet. In this setup, web clients can submit requests to the proxy server, which then forwards them to the web server.

To lessen the demand on web servers, reverse proxy servers can be used to cache pages and images. Additionally, they can be used to divide web content and route requests to several web servers.
