To do so, the server does not send anything. Instead it waits 2ms before closing. The client, on its side, will wait for a response. So it will be blocked. Becauase the client timeout is set to 1ms, HAProxy should always close the client connection because it times out.

# BUG/MINOR: log: pin the front connection when front ip/ports are logged
|
|
#
|
|
# Mathias Weiersmueller reported an interesting issue with logs which Lukas
|
|
# diagnosed as dating back from commit 9b061e332 (1.5-dev9). When front
|
|
# connection information (ip, port) are logged in TCP mode and the log is
|
|
# emitted at the end of the connection (eg: because %B or any log tag
|
|
# requiring LW_BYTES is set), the log is emitted after the connection is
|
|
# closed, so the address and ports cannot be retrieved anymore.
|
|
#
|
|
# It could be argued that we'd make a special case of these to immediately
|
|
# retrieve the source and destination addresses from the connection, but it
|
|
# seems cleaner to simply pin the front connection, marking it "tracked" by
|
|
# adding the LW_XPRT flag to mention that we'll need some of these elements
|
|
# at the last moment. Only LW_FRTIP and LW_CLIP are affected. Note that after
|
|
# this change, LW_FRTIP could simply be removed as it's not used anywhere.
|
|
#
|
|
# Note that the problem doesn't happen when using %[src] or %[dst] since
|
|
# all sample expressions set LW_XPRT.
