It's pointless to set the content type and then to redirect since the
content type the client will get will be the content type of the
*destination* url (i.e., whatever "path" is, presumably the url of the
PDF document).

Why not just link directly to the document in the LocalFS object? 
IIRC, LocalFS allows you to map file extensions to content types. 
Maybe your PDF documents have case-differing extensions (e.g., .pdf
vfs. .PDF)?
