TWebBrowser - How do I load proxy username and password before TWebBrowser.Navig

Hi all,

I have a Delphi6 app that uses TWebBrowser. Everything runs great
until it is installed on a network that pushes all HTTP requests
through a proxy.

I know the proxy port/server/username/password which I store in the
database, but how do I pass those details to the TWebBrowser component
"before" I navigate to the URL?

I also use some Indy components and it's very easy to populate proxy
details, ie TidHTTP.ProxyParams.ProxyServer := 'my.proxyserver.com';
but I can't work it out for setting these params for TWebBrowser??

Thanks for your help.
Cheers,
Jason.
