detect an iframe in OnBeforeResourceLoad()

Postby user6294 » Wed Jun 23, 2021 12:59 pm

Hi

In CefRequestHandler::OnBeforeResourceLoad()

is it possible to detect if an iframe is being loaded (or not), then I want to not insert some additional headers (insert some additional headers) into request being processed.


Many Thanks

Are the subdomains different for the parent and iframe?

I haven't tried this, but you could look at the frame to see if it is a sub-frame, then if yes compare the subdomain of the request against the subdomain of the URL of the main frame for the page.

The CefRequest argument has a GetResourceType method that should help you (e.g. returning RT_SUB_FRAME).
