Oracle iPlanet Web Proxy Server
The Oracle iPlanet Web Proxy Server (OiWPS), formerly known as Sun Java System Web Proxy Server (SJSWPS), is a proxy server software developed by Sun Microsystems (since 2010, Oracle Corporation). Overview. The Oracle iPlanet Web Proxy Server, is a popular HTTP/1.1 Proxy server software developed by Sun Microsystems. OiWPS 4.0 is widely used for proxying, caching, and filtering web content, boosting network security and performance, as well as to protect and secure, and load balance across, content servers. History. Earlier known as "Sun ONE Web Proxy server", the Sun Java System Web Proxy Server 4.0  is a major rewrite of the older 3.x version of Sun's Proxy server, formerly known as "Netscape Proxy Server". The "Netscape Proxy Server" version 3.x was essentially a coupling between the Netscape browser client, responsible for talking to remote servers, and the Netscape web server 4.x, which in turn handled the duty of talking to a client. Support for multithreading was absent, and the Proxy server operated in multi-process mode where each request was handled by a dedicated process. "Sun Java System Web Proxy server 4.0" resulted from a major rewrite of "Netscape Proxy Server" in 2003–2004, when  Sun decided to reinvest in Proxy technology. Switching to Sun web server 6.1's core architecture brought in support for multi-threading while still allowing users to configure the server for multiple processes when so desired. A brand new http client, admin and installer GUI, and localization were the other major changes involved. 4.0 retained other significant features of 3.x such as the ftp client, gopher client, connect client, batch updates, and so on. After acquisition of Sun Microsystems by Oracle Corporation in 2010, Sun Java System Web Proxy Server 4.0 was rebranded as Oracle iPlanet Web Proxy Server 4.0 . Features. Supported Platforms.
