When this field is specified, the access log will be sent only to the logger application and not the access log file specified in previous entry.<br/><br/> The logger application must be defined in <span class="tagP"><a href="#ExtApp_Help">External Apps</a></span> section first. Server-level access logging can only use an external logger application defined at the server level. Virtual host-level access logging can only use a logger application defined at the virtual host level.<br/><br/> The logger process is spawned in the same way as other external (CGI/FastCGI/LSAPI) processes. This means it will execute as the user ID specified in the virtual host's <span class="tagl"><a href="VirtualHosts_Help.html#setUidMode">External App Set UID Mode</a></span> settings and will never run on behalf of a privileged user. <br/><br/> LiteSpeed web server performs simple load balancing among multiple logger applications if more than one instance of a logger application is configured. LiteSpeed server always attempts to keep the number of logger applications as low as possible. Only when one logger application fails to process access log entries in time will the server attempt to spawn another instance of the logger application. <br/><br/> If a logger crashes, the web server will start another instance but the log data in the stream buffer will be lost. It is possible to lose log data if external loggers cannot keep up with the speed and volume of the log stream.</p> <h4>Syntax</h4><p>Select from drop down list</p> </article> </div> <div class="helpitem"><article class="ls-helpitem"><div><header id="accessLog_logFormat"><h3>Log Format<span class="ls-permlink"><a href="#accessLog_logFormat"></a></span><span class="top"><a href="#top">⇑</a></span></h3></header></div><h4>Description</h4><p> Specifies the log format for the access log.
