Is that still supported in Windows, I had thought it was removed for security reasons.
I'm not sure what these reasons could be. In wine it works like that:
- you pass full uri including userinfo to urlmon; - urlmon extracts username/password from it and passes it to wininet; - wininet does its job as usual.
So basically it's just a way to pass userinfo to urlmon as I see it.
