I'm trying to issue a ranged request to retrieve a segment (byte range) of a document stored on Nuxeo but it seems Nuxeo's CMIS Atompub request handler doesn't honor the Range HTTP header.

Is it really not implemented or am I doing anything wrong?

Please note that, in the curl output below, even though the HTTP status is correct (206 Partial Content) the following issues could be found in the response:

• even though I'm requesting the bytes 0 to 10, it returns the whole content (38753 bytes);
• the Content-Length header seems to be missing;
• the Content-Range header seems to be missing;

Edit

I fired the request against demo.nuxeo.com. As of Oct-6-2014, the Nuxeo version at this address is 5.9.5.
