The frames page is already a full page, and of course the relevant parts are loaded separately

Must be reloaded, there is no way to load only in the main frame, the other sub-framework can be used, if the sub-frame has a lot of pages, it must not all loaded

Loading is a must! But the browser caches the static files, so the frames page actually loads the JS file from the buffer
