CL-HTTP displays in the directory listing only files which resource  
types it knows (btw., this is mentioned in the
documentation to HTTP:EXPORT-URL ).

So you need to define the resource type if it is not one of those that  
are defined by CL-HTTP. CL-HTTP uses DEFINE-URL-EXPORT-TYPE for that.

The following would be an example for .owl files. It allows .owl  
and .rdf as OWL files. These files are copied as text files (the copy  
mode). application/owl+xml  is the MIME Type. Alternate extensions is  
a list of other file extensions that could be used.

(http:define-url-export-type :owl-file :owl
   (:application :owl+xml)
   :copy-mode #.http::+standard-text-copy-mode+
   :alternate-extensions (:rdf))
