Sun Java System Web Server 7.0 Update 3 Performance Tuning, Sizing, and Scaling Guide

Default Virtual Server

Virtual servers work using the HTTP 1.1 Host header. If the end user’s browser does not send the Host header, or if the server cannot find the virtual server specified by the Host header, Web Server handles the request using a default virtual server. You can configure the default virtual server to send an error message or serve pages from a special document root.


This setting is tunable when you edit an HTTP listener.
