Stop displaying version info 2004-01-22 - By Donie Kelly

First thing you can do is put in a custom 404 error page. See the archives
or check the docs. It's easy to do.
Second you can override the server header normally sent by tomcat by adding
this line BEFORE any servlet output has been done.
Hope that helps.
Donie
public void doGet (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
try
{
// Override the Server header
res.setHeader("Server", "My Custom header that give no
tomcat version info");
// Your servlet code goes here....
}
catch (Exception ex)
{
res.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
}

Subject: Stop displaying version info
Is there a way I can get tomcat to stop displaying so much info if somebody
hits a 404 or other error? Its a good clue for hackers to start if they know
what version of a popular software I am running. I have it so that apache
displays no info, now just to get tomcat to do the same.
Thanks
Allan
