Subject: Add buffered_logs OFF support to UDP logger (#1315)
X-Git-Tag: SQUID_7_0_1~455
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dc797de0343ecd3f021e1a38968de51c17ea6dbe;p=thirdparty%2Fsquid.git

Add buffered_logs OFF support to UDP logger (#1315)

UDP log module always buffers log entries with a limit of
1400 bytes. Enable the "buffered_logs off" squid.conf
setting to disable this behaviour.
