If resulting URLs can not be guesses easily, the javascript 
function will not be understood.

Simple examples are:
foo.call("/images/img.gif")

More complex examples, not handled:
foo.call(1234)
(that will generate an url with id 1234)

Javascript function are in fact not parsed ; only 
parameters are, and the engine attempt to guess whether it 
has to get the file behind a parameter or not.

But this is rather basic, and sometimes fails..
