URL Mapping has been implemented in Proxy Server 4.0.8, which allows the Proxy Server to act as a reverse proxy. This feature allows Proxy Server to provide a single front-end hostname for back-end application servers. Based on a requester's URI, access is provided to back-end servers.
For more information on URL Mapping, see Reverse Proxy Scenario in Sun Java System Web Proxy Server 4.0.8 Configuration File Reference.
For information on Server Application Functions (SAFs) used in URL Mapping, see Server Application Functions (SAFs) in Sun Java System Web Proxy Server 4.0.8 Configuration File Reference.
