A Web proxy is a service that sits between Web servers and clients. This service receives requests from Web clients and makes requests to Web servers on behalf of the clients.
Sun Java System Web Proxy Server is a freely available HTTP 1.1 proxy server that collects data from the network, determines where that data should go, and distributes it accordingly. Acting as a network traffic manager, it reduces the number of requests to remote content servers and lessens network traffic. The result is that user wait times are lowered and network performance is boosted. It can proxy HTTP 1.0, HTTP1.1 and CONNECT (SSL) requests. It can also serve as a gateway for FTP and SSL servers. The proxy server can also serve as a reverse proxy or a load balancer.
Sun Java System Web Proxy Server is available for the following platforms: HP-UX, AIX, Linux, Solaris, Windows.
