Does the search engine leave HTTP_REFERER?

Question

JavaScript

Task:
there is a page, it should be indexed by a search engine, but when it is not loaded from a frame, it needs to be redirected to the main page. location.href and window.location will not work.
I just want to cut off direct access to the page, preventing it from opening without specifying the main page in HTTP_REFERER ... will it work?
//Nothing evil is planned, you need to open the main page and the frame with the same page that you visited

Answer 1

Googlebot referer does not send. In general, frames are evil.
