+     Set this directive to 'true' to enable the "MS-Author-Via" header
+     in response to an OPTIONS WebDAV request. Early versions of
+     Microsoft Web Folders and Microsoft Office require this header to
+     be present to be able to connect to Zope via 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
+
+     Recent versions of Microsoft Web Folders, updated after January
+     2005, do not require this header anymore, and instead require a
+     "Public" header to be present in reply to the OPTIONS WebDAV
+     request.
+     (http://www.redmountainsw.com/wordpress/archives/webfolders-zope)

+     Set this directive to 'on' to enable sending the "Public" header
+     in response to an WebDAV OPTIONS request.
+
+     Though recent WebDAV drafts mention this header, the original
+     WebDAV RFC did not mention it as part of the standard. Very few
+     web servers out there include this header in their replies, most
+     notably IIS and Netscape Enterprise 3.6.
+
+     Since many best practices documents out in the web mention
+     turning off this header with the subject of "Mask Your Web Server
+     For Enhanced Security", this setting is off by
+     default. Presumably malicious people might take the presence of
+     this header as indication of an IIS Web Server and try to attack
+     your site, so be careful when turning it on.
+
+     Recent versions of Microsoft Web Folders, updated after January
+     2005, *do* require this header to be present in reply to the
+     OPTIONS WebDAV request.

+# Directive: enable-ms-author-via
+#
+# Description:
+#     Set this directive to 'true' to enable the "MS-Author-Via" header
+#     in response to an OPTIONS WebDAV request. Early versions of
+#     Microsoft Web Folders and Microsoft Office require this header to
+#     be present to be able to connect to Zope via 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
+#
+#     Recent versions of Microsoft Web Folders, updated after January
+#     2005, do not require this header anymore, and instead require a
+#     "Public" header to be present in reply to the OPTIONS WebDAV
+#     request.
+#     (http://www.redmountainsw.com/wordpress/archives/webfolders-zope)
+# 
+#     To get a recent Microsoft Web Folders implementation, refer to
+#     Microsoft KB Article 907306.
+#     (Software Update for Web Folders: May 18, 2007).
+#
+# Default: off
+#
+# Example:
+#
+#    enable-ms-author-via on
+
+# Directive: enable-ms-public-header
+#
+# Description:
+#     Set this directive to 'on' to enable sending the "Public" header
+#     in response to an WebDAV OPTIONS request.
+#
+#     Though recent WebDAV drafts mention this header, the original
+#     WebDAV RFC did not mention it as part of the standard. Very few
+#     web servers out there include this header in their replies, most
+#     notably IIS and Netscape Enterprise 3.6.
+#
+#     Since many best practices documents out in the web mention
+#     turning off this header with the subject of "Mask Your Web Server
+#     For Enhanced Security", this setting is off by
+#     default. Presumably malicious people might take the presence of
+#     this header as indication of an IIS Web Server and try to attack
+#     your site, so be careful when turning it on.
+#
+#     Recent versions of Microsoft Web Folders, updated after January
+#     2005, *do* require this header to be present in reply to the
+#     OPTIONS WebDAV request.
