Sun Java System Portal Server 7.1 Deployment Planning Guide

Proxylet

Proxylet is a dynamic proxy server that runs on a client machine. Proxylet redirects a URL to the Gateway. It does this by reading and modifying the proxy settings of the browser on the client machine so that the settings point to the local proxy server or Proxylet.

It supports both HTTP and SSL, inheriting the transport mode from the Gateway. If the Gateway is configured to run on SSL, Proxylet establishes a secure channel between the client machine and the Gateway. Proxylet uses the Java 2 Enterprise Edition API if the client JVM is 1.4 or higher or if the required jar files reside on the client machine. Otherwise it uses the KSSL API.

Proxylet is enabled from the Portal Server administration console where the client IP address and port are specified.

Unlike Rewriter, Proxylet is an out-of-the-box solution with very little or no post-installation changes. Also Gateway performance improves because Proxylet does not deal with web content.
