/**
 * Unit test for alternate docroot support and welcome pages.
 * See
 *   https://glassfish.dev.java.net/issues/show_bug.cgi?id=6731
 *   ("how to protect files residing in docroot in Glassfish")
 * for details.
 *
 * This test configures the virtual server "server" with the following
 * alternate docroot properties:
 *
 *   <property
 *     name="alternatedocroot_1"
 *     value="from=/mytest dir=/tmp"/>
 *   <property
 *     name="alternatedocroot_2"
 *     value="from=/mytest/* dir=/tmp"/>
 *
 * and ensures that a request with a URI of the form /mytest will first be
 * redirected to "/mytest/", before the contents of the welcome page located
 * in "/tmp/mytest/index.jsp" in the local filesystem will be served.
