Steve Gibson from GRC.COM recently created a free tool that queries
various pieces of information from a web site, ftp site etc.
http://grc.com/id/idserve.htm
I thought it was a nice addition. You might find something in there
that shows why your getting 0 bytes returned.

Subject: [isalist] ISA and empty Content-Lenght: header
http://www.ISAserver.org
Hi All,
I've got a problem with a site where downloads are resulting in 0 byte
files. Upon closer look at the response headers from the site (IIS5)
it's
sending an empty Content-Length header, response code of 200 OK. My
understanding of the HTTP1.1 protocol is that if a content-length header
is
going to be sent it has to actually have a value with it (>=0). So am I
not
going nuts in thinking this is an IIS / application problem and not an
ISA
problem? Biggest reason I ask is that when bypassing the ISA server the
file comes down as expected with the same headers.
Here is the complete set of response headers from the site:
HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Thu, 28 Feb 2002 21:45:25 GMT
Content-Disposition: attachment; filename=<insert filename here...>
Content-Lenght:
Content-Type: application/octet-stream; Charset=UTF-8
Set-Cookie: <big long asp session cookie goes here...>
Cache-control: private
