The default HED implementation is in 'webdav.Resource': it makes some assumptions which are not appropriate. You can override it for your own content objects: here is what App.ImageFile does:: security.declarePublic('HEAD') def HEAD(self, REQUEST, RESPONSE): """ """ RESPONSE.setHeader('Content-Type', self.content_type) RESPONSE.setHeader('Last-Modified', self.lmh) return '' IMNSHO, there is absolutely no general way for a dynamic application to satisfy clients that use HEAD instead of conditional get: the semantics they rely on are meaningless for dynamically generated content.
