Hi Oleg,
I'm not able to log anything in the http log file.
I'm using log4j2, and these are my appender and logger:
<File name="HTTP_LOG" fileName="${sys:log.dir}httpClient5.log" append="true"
immediateFlush="true">
<PatternLayout><Pattern>%m%n</Pattern></PatternLayout>
</File>
<Logger name="org.apache.hc" level="debug" includeLocation="false"
additivity="false">
<AppenderRef ref="HTTP_LOG"/>
</Logger>
The ' httpClient5.log' is correctly created, but nothing is logged when I start
and stop my HttpClient instance. Is the logger name 'org.apache.hc' correct?
Thanks,
Joan.

Please post a test app reproducing the problem outside the servlet container.
