Stop complaining! Why not just patch it. It is trivial to patch. See Re: Who wants to help me adjust LinkExtor::Simple? for details of how to make LinkExtor::Simple extract any links you like. Then call the style, extjs methods you just created in the same way $extor->img gets looped over inf HTML::Size

Although you can easily do it it is relevant to remember that CSS, JS, icons, button images, will generally get cached locally so while they might be part of a page they are typically reusable elements.

The ultimate way to do it is to use a logging proxy of some sort. HTTP::Proxy with HTTP::Recorder might be an option.
