Redirect to the secure port within a serlvet

[Antony GUILLOTEAU]

I wanted to simulate a CLIENt-CERT realm to the browser with serlvet 
(response.setHeader("WWW-Authenticate", "BASIC realm=\"myName\"")) but it seems 
not possible. So I want to basically redirect my request to SSL. 

I wish know how to redirect a request to the secure port within a serlvet but I 
don't want use init-parameter in the web.xml and so one.

Thanks
