Hi all, two weeks ago, I submitted a patch against Zope-2.9.1 that makes the 'MS-Author-Via' header configurable in zope.conf ( http://www.zope.org/Collectors/Zope/1441 ) but I did not hear a single comment about it, so I'm guessing nobody noticed it. As the original collector entry referred to Zope 2.7.2, should I submit it in its own collector entry for it to be taken into account? The patch : http://www.zope.org/Collectors/Zope/1441/diff-Zope-2.9.1-Zope-2.9.1-patch-we... It is documented as following : Set this directive to 'on' to enable WebDAV compatibility for Microsoft software. Microsoft implementation of WebDAV uses the non-standard 'MS-Author-Via' header to determine if it should use WebDAV. This is disabled by default since it makes a lot of standards-compliant things unhappy AND it tricks Microsoft Office into trying to edit Office files stored in Zope via WebDAV even when the user isn't allowed to edit them and is only trying to download them. Check this collector entry for more information: http://www.zope.org/Collectors/Zope/1441 Regards, Patrick.
