Working with Log Fields in W3C Access Logs
When defining a W3C access log subscription, you must choose which log fields 
to include, such as the ACL decision tag or the client IP address. You can include 
one of the following types of log fields:
Predefined. The web interface includes a list of fields from which you can 
choose. For more information, see 
.
User defined. You can type a log field that is not included in the predefined 
list. For more information, see 
Most W3C log field names include a prefix that identifies from which header a 
value comes, such as the client or server. Log fields without a prefix reference 
values that are independent of the computers involved in the transaction. 
 describes the W3C log fields prefixes.
For example, the W3C log field “cs-method” refers to the method in the request 
sent by the client to the server, and “c-ip” refers to the client’s IP address.
