How do I get information from an HTTP server protected by a username and password?

I log in to the site using a CustomWebView. I'm entering the user's password.EvaluteJavaScript. Visually, I see that the login is completed, the protected part of the site is available. But get(responseContent) returns an html page. How do I get in get(responseContent) what the computer browser shows?


you can try to use a WebViewer (GoToUrl) to display it.

I tried WebViewer and CustomWebView to display the result is the same.

This usually is an error message
Unfortunately you forgot to post the complete response content, so currently we can't see rhe error message. .
