+# commit 7b6cc52784526c32efda44b873a4258d3ae0b8c7
+# BUG/MINOR: lua: Bad HTTP client request duration.
+#
+# HTTP LUA applet callback should not update the date on which the HTTP client requests
+# arrive. This was done just after the LUA applet has completed its job.
+#
+# This patch simply removes the affected statement. The same fixe has been applied
+# to TCP LUA applet callback.
+#
+# To reproduce this issue, as reported by Patrick Hemmer, implement an HTTP LUA applet
+# which sleeps a bit before replying:
+#
+#   core.register_service("foo", "http", function(applet)
+#       core.msleep(100)
+#       applet:set_status(200)
+#       applet:start_response()
+#   end)
+#
+# This had as a consequence to log %TR field with approximatively the same value as
+# the LUA sleep time.
