+# commit 70d318c
+# BUG/MEDIUM: lua: possible CLOSE-WAIT state with '\n' headers
+#
+# The Lua parser doesn't takes in account end-of-headers containing
+# only '\n'. It expects always '\r\n'. If a '\n' is processes the Lua
+# parser considers it miss 1 byte, and wait indefinitely for new data.
+#
+# When the client reaches their timeout, it closes the connection.
+# This close is not detected and the connection keep in CLOSE-WAIT
+# state.
+#
+# I guess that this patch fix only a visible part of the problem.
+# If the Lua HTTP parser wait for data, the timeout server or the
+# connectio closed by the client may stop the applet.
