Proxylet
Chapter 2 Portal Server Secure Remote Access Architecture 49
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 JSSE 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 Access Manager 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.
NOTE You can run multiple Rewriter Proxies to avoid a single point of
failure and achieve load balancing.
