Allowing Clients to Check IP Address

To maintain your network’s security, your client might have a feature that restricts access to only certain IP addresses. To allow your clients to use this feature, the Proxy Server provides support for checking Java IP Address.

Checking Java IP Address allows clients to query the Proxy Server for the IP address used to reroute a resource. Because DNS spoofing often occurs with Java Applets, this feature enables clients to see the true IP address of the origin server.

When this feature is enabled, the Proxy Server attaches a header containing the IP address that was used for connecting to the destination origin server. For example. if this feature is enabled, and if the request contains a "Pragma: dest-ip" header, the Proxy Server includes the IP address of the origin server as the value of a "Dest-ip:" header.

For information about the Server Application Function (SAF) used for checking Java IP Address, see java-ip-check in the section ObjectType in Oracle iPlanet Web Proxy Server 4.0.14 Configuration File Reference
