2# BUG/MEDIUM: lua: possible CLOSE-WAIT state with '\n' headers
3#
4# The Lua parser doesn't takes in account end-of-headers containing
5# only '\n'. It expects always '\r\n'. If a '\n' is processes the Lua
6# parser considers it miss 1 byte, and wait indefinitely for new data.
7#
8# When the client reaches their timeout, it closes the connection.
9# This close is not detected and the connection keep in CLOSE-WAIT
10# state.
11#
12# I guess that this patch fix only a visible part of the problem.
13# If the Lua HTTP parser wait for data, the timeout server or the
14# connectio closed by the client may stop the applet.
