 + 
 +When the ''CustomLogFormat'' setting is not used, the default format is the Apache "Combined Log Format". 
 + 
 +When the ''CustomLogFormat'' setting is used, the supported [[https://httpd.apache.org/docs/current/mod/mod_log_config.html|Apache Custom Log Format directives]] are: 
 + 
 +| %% | The percent sign |  
 +| %a | Client IP address of the request |  
 +| %B | Size of response in bytes, excluding HTTP headers. |  
 +| %b | Size of response in bytes, excluding HTTP headers. In CLF format |   
 +| %h | Remote hostname or IP address |  
 +| %H | The request protocol |  
 +| %l | Remote logname (from identd, if supplied) |  
 +| %p | Server TCP port number | 
 +| %r | First line of request |  
 +| %s | Status |  
 +| %t | Time the request was received, in the format [18/Sep/2011:19:18:28 -0400] |  
 +| %u | Remote user if the request was authenticated |  
 +| %v | The canonical ServerName of the server serving the request. (the vhost) |  
 +| %{remote}p | the client's actual port |  
 +| %{Referer}i | the HTTP Referer [sic] header line |  
 +| %{User-agent}i | the HTTP User-agent header line | 
 + 
 +Note: Double-quote characters used in the format string do **not** need to be escaped (i.e. with a backslash) 
 + 
 +Example: 
 + 
 +This is the equivalent of Apache's combined log format which is used by default. 
 + 
 +    CustomLogFormat = %h %l %u %t "%r" %s - "%{Referer}i" "%{User-agent}i" 
 + 
 +This is the equivalent of Apache's vhost_combined log format.
