I open the developer tools on the site page. I'm looking at the recaptcha__ru.js script. In "Headers" there is "Request Headers", and there - "Referer". Is it possible to force a value change in the referer field?
Cyrillic domain. In this field, it is in Edge and IE in CP866 encoding, and not in punycode.
An error is displayed in the console (see screenshot). I suspect because of this. How to change the encoding of http headers (in particular what is in the referer header)?
