This feature is new in the Software Express pilot program and in the Solaris 9 12/02 release. This feature is included in the Solaris 10 3/05 release.
The Solaris Network Cache and Accelerator (NCA) kernel module now supports multiple instances of a web server. This support enables you to use a Solaris machine to perform Internet protocol (IP) address-based virtual web hosting. The Solaris software uses a single configuration file, /etc/nca/ncaport.conf, to map NCA sockets to IP addresses.
For further information, see the ncaport.conf(4) man page.
