Fabrizio Giustina commented on MAGNOLIA-3201:
---------------------------------------------
well, it's not actually for "debugging": this informations are added to the
error logs (usually only for error/fatal level and only in the mail appender
when enabled) and are particularly useful for production enviroments.
It's a totally different thing from the DumpsHeadersFilter which have to be
enabled explicitly and has a big performance overhead.
This doesn't hurt and doesn't add any performance overhead, so it's nice to
have it available as a default...
This is a sample error mail that can be obtained with this filter enabled:
