Using the IntelliJ proxy settings from a plugin

Hi all,

I want to enable proxy support for my ivy integration plugin and have it
use the IntelliJ proxy server settings when configured. I browsed through
the openapi packages and found the HttpConfigurable class. I've changed my
code to call the following method befor accessing an url:

private void prepareURL(URL dest) throws IOException {
HttpConfigurable.getInstance().prepareURL(dest.toExternalForm());
}

but it does not seem to do the trick; it just acts as if no proxy was configured.

Can anyone point me in the right direction? Or does anyone know of a plugin
that already does a similar thing and from which I could learn?

Thanks!

Guy
