servlet and proxy

[Maxime]

Hi

URL Connections establish by my servlets must pass throw a proxy server (HTTP/HTTPS)

a simple 
System.getProperties().put("proxySet","true" );
System.getProperties().put("proxyHost",host);
System.getProperties().put("proxyPort",port);
in a servlet "load-on-startup" doesn't work.

How can i do that ?

thanks
