From 531485c08ffb15b939a28ecf47090e4c93341d1b Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Tue, 16 Sep 2014 15:48:15 +0200 Subject: [PATCH 05/13] DOC: indicate in the doc that track-sc* can wait if data are missing Since commit 1b71eb5 ("BUG/MEDIUM: counters: fix track-sc* to wait on unstable contents"), we don't need the "if HTTP" anymore. But the doc was not updated to reflect this. Since this change was backported to 1.5, this doc update should be backported as well.
