WebDAV HEAD requests are not handled correctly

Hello,

Microsoft Office use HEAD method request during webdav access (verified with wireshark), then a GET one. But Nuxeo never responds to HEAD requests. Indeed I activate debug for webdav module, and I dont see HEAD request coming in logs (i have GET, OPTIONS, PROPFIND...) :

2014-10-17 09:39:54,940 DEBUG [http-bio-0.0.0.0-8080-exec-26] [org.nuxeo.ecm.webdav.resource.RootResource] OPTIONS /nuxeo/site/dav/john.doe/ 2014-10-17 09:40:01,353 DEBUG [http-bio-0.0.0.0-8080-exec-26] [org.nuxeo.ecm.webdav.resource.RootResource] LOCK /nuxeo/site/dav/john.doe/Toto5.docx 2014-10-17 09:40:01,497 DEBUG [http-bio-0.0.0.0-8080-exec-24] [org.nuxeo.ecm.webdav.resource.RootResource] GET /nuxeo/site/dav/john.doe/Toto5.docx

The problem is that without HEAD response Office is very slow (awaiting timeout) or is opening file in Read Only.

Is it possible to make Nuxeo responds to HEAD requests on WebDAV access ?

Thanks.
