Capture client request HEADERS with QWebEngineView

[lgeffect]

There is a need for interception of the created HTTP request and reading its HEADERS !. The Internet found it: https://stackoverflow.com/questions/40309105/capture-server-response-with-qwebengineview , and it is impossible to access the headers that were generated on the page, but you can only insert your own. In this regard, I found the correct information only for the old QWebView, and QWebEngineView does not.
