From 97cc70d7285526ae2ee3b3bac425eb031c4c0321 Mon Sep 17 00:00:00 2001 From: Giuseppe Castagno Date: Thu, 13 Oct 2016 09:34:19 +0200 Subject: tdf#102499 (7): Caching connect timeout or cannot connect. An unofficial HTTP response status code is defined and used internally in LibreOffice WebDAV ucp provider in order to catch either the DAVException::DAV_HTTP_TIMEOUT state or the DAVException::DAV_HTTP_CONNECT state.
