howdy fellas,

 when downloading file using the downloadfile (GetFile?) api, what  distinguish between failure and a successful download of a file with one of the two following contents snippets:

 <response>  
   <result>-20</result>  
     <message>Requested resource "path/resourcename" not found</message>
  </response>
  
  <response>
    <result>-29</result>
    <message>user “user” not found </message>
  </response> 

as a suggestion, only for this request, can we have the server passing a http header that actually indicates a success or failure?

My issue with downloadfile is to tell the size of what is being downloaded. The response from downloadfile looks like this:

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Set-Cookie: r_sessionid=1186609292783_3221551951820651387
Set-Cookie: edu.yale.its.tp.cas.client.filter.user=Voidmain
Server: Omnidrive State representation engine v0.7.0
Content-Type: application/octet-stream
Transfer-Encoding: chunked
Date: Wed, 08 Aug 2007 21:41:32 GMT

Without Content-Length being passed back in the header i'm unable to determine the total bytes of what is being downloaded.

An example of a response with Content-Length looks like the following:

HTTP/1.0 200 OK
Date: Wed, 08 Aug 2007 16:39:11 GMT
Server: Apache/2.0.52 (Red Hat)
Cache-Control: max-age=315360000
Expires: Mon, 28 Jul 2014 23:30:00 GMT
Last-Modified: Sat, 28 Jul 2007 20:03:44 GMT
Accept-Ranges: bytes
Content-Length: 6954
Content-Type: image/jpeg

X-Cache: HIT from photocache203.flickr.sp1.yahoo.com
Via: 1.0 photocache203.flickr.sp1.yahoo.com:80 (squid/2.6.STABLE10)
Connection: keep-alive

Without the Content-Length being returned the only alternative I see is to get the file properties before downloading. Is there something i'm missing here? Can you get the Content-Length without a header value?

Thanks for any help. -Steve

So i've figured out that the Content-Length will not show up if    Transfer-Encoding: chunked

Now it looks like I have the size of the chunk data:

Example Response:
Server: Apache-Coyote/1.1
Server: Omnidrive State representation engine v0.7.0
Content-Type: application/octet-stream
Transfer-Encoding: chunked
Date: Thu, 09 Aug 2007 17:07:37 GMT

It doesn't look like there is anyway to figure out what the total length of the message body will be based on the Chunked stream of data. Can anyone confirm that so i can stop looking?

Thanks much -Steve
