[Ur] howto serve arbitrary files (PDF/ icons), and more

[Marc Weber]

1)
Which is the ur way to serve arbitrary files such as content-type
application/pdf ?

The PDF files could be 

- generated on the fly (eg by running latex, lout, ...)

- read from a file?

  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.
 

2)
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.

3)
How to specify the "index" file which will be used if no path is given?
