How to set up automatic authorization on the server in GeckoFx (c#)?

Question

C++ / C#

I am writing a project - my own browser in C # WPF. It is necessary to configure automatic user authorization on the server. But with all attempts, a window pops up:
"Authentication Required"
A username and password are being requested by https://test.test.st. The site says: "OracleServer".
Login: ...
Password: ...
Is it possible to set login and password directly through c# code?
ps on the site, the .htaccess file exists and it is registered correctly, since if you log in through a regular browser, login and password are not required.

Answer 1

What prevents you from looking in the browser console what happens during authorization? What headers it sends, what it receives.
PS Normal, not your browser.
