CGIs are not in the picture at all. By definition, a context (from Tomcat's
perspective,
or the perspective of any servlet container) consists only of servlets (plus things
that
get turned into servlets, like JSP pages, or executed by servlets) You will need to
use
sendRedirect() to transfer control to a CGI script.
