This is a problem regarding webview plugin.
The scenario as below:
If we want to open an URL which need the authorization, server side will return a 401 response.
In this case, the webview be rendered as a blank page rather than alert a dialog to ask user input the authorization information (User ID, password) which just like what the mainstream browser do.
Is there an existing solution to cover this scenario or we have to make the secondary development to handle this case if we use the plugin
