In such a case, the reverse proxy may need to rewrite the URLs in each web page (translation from externally known URLs to the internal locations). Load balancing: the reverse proxy can distribute the load to several web servers, each web server serving its own application area.This problem can partly be overcome by using the SubjectAltName feature of X.509 certificates. Furthermore, a host can provide a single 'SSL proxy' to provide SSL encryption for an arbitrary number of hosts, removing the need for a separate SSL server certificate for each host, with the downside that all hosts behind the SSL proxy have to share a common DNS name or IP address for SSL connections. Encryption/SSL acceleration: when secure websites are created, the Secure Sockets Layer (SSL) encryption is often not done by the web server itself, but by a reverse proxy that is equipped with SSL acceleration hardware.There are several reasons for installing reverse proxy servers: The use of reverse originates in its counterpart forward proxy since the reverse proxy sits closer to the web server and serves only a restricted set of websites. All traffic coming from the Internet and with a destination of one of the neighborhood's web servers goes through the proxy server. Reverse proxies are installed in the neighborhood of one or more web servers. The response from the proxy server is returned as if it came directly from the original server, leaving the client with no knowledge of the original server. Reverse proxies forward requests to one or more ordinary servers that handle the request. Those making requests connect to the proxy and may not be aware of the internal network.ДЄ reverse proxy (or surrogate) is a proxy server that appears to clients to be an ordinary server. Open proxies ДЄ reverse proxy taking requests from the Internet and forwarding them to servers in an internal network. A reverse proxy commonly also performs tasks such as load-balancing, authentication, decryption and caching. A reverse proxy is usually an internal-facing proxy used as a front-end to control and protect access to a server on a private network. A forward proxy is an Internet-facing proxy used to retrieve data from a wide range of sources (in most cases anywhere on the Internet). A proxy server that passes unmodified requests and responses is usually called a gateway or sometimes a tunneling proxy. 3.8 Comparison to network address translatorsДЄ proxy server may reside on the user's local computer, or at any point between the user's computer and destination servers on the Internet.A proxy server thus functions on behalf of the client when requesting service, potentially masking the true origin of the request to the resource server. Proxies were devised to add structure and encapsulation to distributed systems. This serves as a method to simplify or control the complexity of the request, or provide additional benefits such as load balancing, privacy, or security. Instead of connecting directly to a server that can fulfill a requested resource, such as a file or web page, the client directs the request to the proxy server, which evaluates the request and performs the required network transactions. In computer networking, a proxy server is a server application that acts as an intermediary between a client requesting a resource and the server providing that resource. Bob does not know to whom the information is going, which is the reason that proxies can be used to protect privacy. Communication between two computers (shown in grey) connected through a third computer (shown in red) which acts as a proxy server.
