Sun Java System Web Server 6.1 SP9 NSAPI Programmer's Guide

AuthTrans

When the server receives a request, it executes the AuthTrans directives in the default object to check that the client is authorized to access the server.

If there is more than one AuthTrans directive, the server executes them all (unless one of them results in an error). If an error occurs, the server skips all other directives except for Error directives.
