Which is the ur way to serve arbitrary files such as content-type
application/pdf ?
That would be the function [Basis.returnBlob].
Eg adding "allow url css/*" to the configuration file a link to
css/css.css complied. Status is still 404 (not found)
I also tried adding path css=./css
strace showed that urweb didn't even try to load a css.css file.
Ur/Web executables contain no default web server functionality for
reading from static files. I recommend hosting static content with a
traditional web server, possibly one that proxies to your application
(via HTTP or FastCGI) for the dynamic content.

Does urweb support the system() FFI command? If not is there a small
example which could help getting started with exploring FFI?
system could be used for many quick& dirty implementations.
Dirty indeed. ;) Ur/Web is designed to be completely transactional,
where any action taken can be rolled back. A general 'system' function
obviously can't satisfy this property.
If you're willing to take your chances with non-undoable commands being
run multiple times as your page handler restarts for various reasons,
you might want to start from this example:

How to specify the "index" file which will be used if no path is given?
No such functionality in Ur/Web. I again recommend using a traditional
web server or proxy for this.
