anchor.diff:  
   If logging is set up to use log files then the server will check that the log file directory exists and is writable.
   If this check fails, then the server will not start and will report the failure to another available channel like standard out.

  +====
  +Neo4j server now has *experimental* support for logging full request and response bodies. It is enabled by setting
  +the following property in _neo4j-server.properties_:
  +
  + org.neo4j.server.http.unsafe.content_log.enabled=true
  +
  +The following logging pattern must also be specified in _neo4j-http-logging.xml_:
  +
  + <pattern>%fullRequest\n\n%fullResponse</pattern>
  +
  +This functionality fully duplicates HTTP requests and responses, logging them out to disk. As such it is
  +*strongly advised* to not run this in a production setting because of the potential to constrain performance.
  +However it can prove useful in testing and pre-production environments.

  The main configuration file for the server can be found at _conf/neo4j-server.properties_.
  This file contains several important settings, and although the defaults are sensible

  ====
  By default the HTTP logger uses +http://en.wikipedia.org/wiki/Common_Log_Format[Common Log Format]+
  meaning that most Web server tooling can automtically consume such logs. In general users should only enable HTTP logging,
  select an output directory, and if necessary alter the rollover and retention policies.

  To enable HTTP logging, edit the _conf/neo4j-server.properties_ file to resemble the following:
