@rmarinho I'm going to assume you triaged this given you self-assigned it. Lemme know if that's not the case.

Sadly this also drops any url based basic authentication.
url of “https://user:pwd@server.com/resource” drops the user:pwd part.
This worked on Xamarin 2.5 (cant confirm if 3.0 was affected, but 3.1 was tested and the url is changed, dropping the creds.

Will this change also include a fix for this use case?
