Redirect all subdomains to one subdomain

Hi, Im using resin 2.1.11
I have a host configured with IP that accept all the subdomains within a
domain (configured throw DNS to that server)
I need to configure resin in order to accept all this subdomains, but to
redirect them all to one subdomain.
For example, I have a.foo.com , b.foo.com and c.foo.com , I accept them all,
but I would like all of them to be redirected to a.foo.com
¿Is this possible?
Thanks, and excuse me for my bad english...
