Laurent, I will be more than happy to help you as far as HttpClient is concerned, but I have always shunned away from applet programming at all costs, and therefore can be of little assistence here. I _suppose_ if the browser is equipped with the Sun's Java plugin, you _may_ be able to query the http.proxyHost and http.proxyPort system properties. But this is no more than a wild guess on my part.
