I need to download html pages and its files (js, css, images, etc) in format
similar to browser downloads.
Meaning if I download a web page <http://website.url/some_directory/some_page>,

I would like to get some_page in site structure format (which I can get) and
also all page files in a folder some_page inside some_directory. The page
files js, css, images can be from anywhere even outside domain but I want them
in folder some_page.
