It would depend on where the dialog originated from. In some cases where the
server requires the client to provide authentication, it sends back a header
like this:
WWW-Authenticate: Basic realm="My Realm"
"HTTP/1.0 401 Unauthorized"
Typically this is used to authenticate access to a restricted part of a web
site on an HTTP server.
Most web browsers recognise this by popping up a dialog box asking for your
username and password. The browser then re-requests the same page passing
back the information from the dialog.
I don't know how proxy servers request authentication, whether they do it by
sending HTTP headers or what. If you are using an HTTP component to connect
then I would have assumed you could see the headers it sends back.
