The WWW superservice supports four log file formats which makes it possible to support a wide range of web servers like Apache™, IIS or Boa™.
Common Log Format (CLF) is a standard log format that was originally implemented in the CERN httpd web server but that is supported nowadays by most web servers. Apache™, IIS and Boa™ can be configured to log in that format.
The Common Log Format has the following format:
remotehost
rfc931
authuser
[date
] "request
"status
bytes
where the fields have the following meaning:
remotehost

rfc931
The result of an ident lookup on the host. This is usually not used.
authuser
