Hmm Not that simple:

response for
www.officeclub.co.uk:8080/tracker.cfm?pageselected=/pdfs/Staedtlerterm.pdf:
code=302
>>> HTTP/1.1 302 Found
>>> Date: Tue, 24 Sep 2002 10:14:54 GMT
>>> Server: Apache/1.3.11 (Win32)
>>> Location: /pdfs/Staedtlerterm.pdf
>>> Connection: close
>>> Transfer-Encoding: chunked
>>> Content-Type: text/html

However:

response for www.officeclub.co.uk:8080/pdfs/UHUterm.pdf:
code=200
>>> HTTP/1.1 200 OK
>>> Date: Tue, 24 Sep 2002 10:15:32 GMT
>>> Server: Apache/1.3.11 (Win32)
>>> Last-Modified: Fri, 30 Aug 2002 15:39:15 GMT
>>> ETag: "0-127b2-3d6f91a3"
>>> Accept-Ranges: bytes
>>> Content-Length: 75698
>>> Connection: close

The MIME time seems to be working ok?
Any other suggestions?
