[Seaside] referencing resource/data/foo.pdf

[Rob Whitfield]

I am generating pdf files with my seaside application.  By having a link to 
the following I could open the pdf from my browser.

/seaside/apdf/resource/foo.pdf

As part of an effort to better organize things I moved the generated pdf 
down one directory level to:

/seaside/apdf/resource/data/foo.pdf

Now I can no longer view the pdf via the link.  I get an error that the 
file is zero length (it is definitely a valid file).  Seems like seaside 
has problems accessing or delivering files below the default level.  Does 
anyone have a suggestion for getting this to work?
