Serve static XML files how?

Hi,

a Javascript in one of my Rails templates needs to load a static XML
file. I tried several places to put the actual XML file, and I also
tried to make the file a rails template (tried both .rhtml and .rxml)
and access it via a controller action. None of these ways worked. Does
the lighttpd server know how to serve XML files, or do I need to
configure it first? Or, is there a good workaround?
