/**
 * Unit test for 6324911 ("can not migrate all virtual server functions
 * from 7.1 to 8.1. (eg: custom error page)").
 *
 * The supporting build.xml assigns the following property to the virtual
 * server named "server":
 *
 *   send-error="path=default-web.xml reason=MY404 code=404"
 *
 * As a result of this setting, any 404 response must have a reason string of
 * MY404, and must provide the contents of the
 * domains/domain1/config/default-web.xml file in its body.
 *
 * The code below does not check the entire response body. Instead, it only
 * checks for the presence of a line that starts with "<web-app xmlns=",
 * which is contained in default-web.xml, and uses its presence as an
 * indication that the response contains the expected body.
