![]() Additionally, it also helps you avoid getting inundated with unwanted ads while browsing the world wide web. This helps add a layer of security that protects the user and the internal network from unauthorized access via the Internet.īy concealing your IP address and location information, proxies protect you from the collection of IP-specific data. Proxies conceal your IP address and other location information and act like a firewall between the user and the Internet. Using a proxy server is beneficial for organizations in a number of ways the key benefits include: Unlike forward proxies, which handle client requests and forward them to the internet, access proxy servers forward client requests to backend servers within a private network.Īccess proxy servers are typically used for handling authentication and authorization for client requests, load balancing, content caching and compression, and to handle SSL/TLS encryption and decryption. SMTP (Simple Mail Transfer Protocol) proxy server, which handles email traffic.Īn access proxy server operates as an intermediary between client devices and backend servers or services. HTTP (Hypertext Transfer Protocol) proxy server, which handles HTTP traffic,įTP (File Transfer Protocol) proxy server, which facilitates FTP file transfers between clients and FTP servers.ĭNS (Domain Name System) proxy server, which intercepts DNS requests made by client devices and forwards them to DNS servers. Protocol proxy servers are typically used to provide additional functionality and security, or to enhance the performance tailored to the specific protocols they support.Ĭommon examples of protocol proxy servers include: As the name suggests, protocol proxies are designed to work with only specific protocols or applications. ![]() Protocol proxy servers or protocol gateways are proxy servers that operate at the application layer of the network protocol stack. Thus they are able to not only hide the client’s IP address and geographical location but also avoid targeted marketing and allow access to web content censored in the user's location. Additionally, anonymous proxies also routinely change IP addresses when making requests to web servers. They conceal the client's IP address and high-anonymity proxies do not identify themselves as proxies to web servers. They are also configured to either ‘allow' or ‘deny' a user's request and follow the usual process to either complete the request or return an error or redirect message.Īnonymous proxies are the most common type of proxy servers. Reverse proxies are generally used to monitor and restrict access to servers containing sensitive data. it passes requests from the Internet via a firewall to users in an internal network. But if the request is denied, the proxy returns an error or redirect message.Ī reverse proxy server is essentially the reverse of a forward proxy, i.e. If the request is allowed, then the proxy follows the usual process of checking the cache and then forwards the request to the destination server. A forward proxy is typically configured to either ‘allow' or ‘deny' a user's request. It receives requests from users on an internal network and passes them on to the Internet via a firewall. The following are the most common types of proxy servers:Ī forward proxy server is a type of proxy that controls access to content on the Internet. There are a wide variety of servers categorized based on traffic flow, anonymity level, application, etc. The response to that request comes back to the proxy server, which forwards the data received from the website to your computer. So, when you want to visit a website, your computer sends a request for the web page to the proxy server instead of requesting it directly. Additionally, by requesting resources on behalf of the client, proxy servers can mask the true origin of the request to the resource server, improving privacy.įor example, proxy servers are commonly used as a gateway separating end users from the Internet such that all web traffic goes through the proxy server rather than directly to the websites you visit. The function of a proxy server is to simplify or control resource requests and to provide functionalities such as load balancing and security. When the proxy server receives a request from the client, it evaluates the request, forwards it to the server, and completes the required network transaction. A proxy server is a server application that functions as an intermediary between a client, which requests a resource, and a server, which provides that resource.
