[plt-scheme] web-server with a single servlet

Dear all,

A question about configuring web-server (WS):

I would like to use WS in a slightly non-standard configuration: I  
want a single servlet to respond to *all* requests to a particular  
port on a machine. For example, if I'm running my server on localhost  
port 8080, I want all requests to:

   http://localhost:8080
   http://localhost:8080/abc
   http://localhost:8080/def
   http://localhost:8080/ghi/jkl

and so on to go to the same servlet. I only have one servlet, and I'm  
quite happy to serve static content by getting it to pipe files back  
to the user.

After looking at the docs and source, I don't think WS can be  
configured to behave in this way: from what I understand, the name of  
the servlet file has to occur somewhere in the URL:

   http://localhost:8080/servlets/abc.ss

I don't want to do this because I want super-user-friendly URLs as  
entry points. I've tried using Apache and mod_proxy to translate URLs  
and forward requests to WS, but for various reasons (including  
problems with large file uploads) this has turned out to be problematic.

Can anyone suggest a way of configuring WS in this way? Failing that,  
I may be looking at creating a hacked version of WS for this project:  
I'd appreciate any advice you can offer.

Many thanks,

-- Dave
