subdomain in glassfish

Hi

I want to set up a virtual server for subdomain

my domain is redirected from
pradyut.dyndns.org

to pradyut.dyndns.org/WebApplicationSecurity

using a virtual server whose default web module is
WebApplicationSecurity
I have used the string "${com.sun.aas.hostName},pradyut.dyndns.org"
in the hosts of the virtual server

now to the question
if someone enters "newa.pradyut.dyndns.org"
how can i redirect to

pradyut.dyndns.org/WebApplicationSecurity/newa

or "*.pradyut.dyndns.org"
redirects to pradyut.dyndns.org/WebApplicationSecurity/*

Thanks
Pradyut

hey if you got the solution please post it..
i am having similar issue..

no solution with admin console...

by using a filter and coding in that filter

request.getUrl and then parsing the url and redirecting appropriatly...

Cheers...
