Get all responses from a page

[DerFichtl]

Hey. Is it possible to get all responses (images, stylesheets, ...) from a page to check for content length, status, ...

I tried to fiddle around with $page->on('response') and $page->on('load') to capture and return the repsonses to php. But that seems not the right way. Maybe you have an idea how to do that? Thx.
