Specifies

The first line of the request.

For requests that were redirected internally, this is the status of the original request.

The time, in common log format (standard English time format).

The time, in the form given by format, must be in the strftime(3) format. For format descriptions, see Time Format Definition on page 121.

The time taken to serve the request, in seconds.

The remote user (from auth; may be bogus if return status (%s) is 401).

The URL path requested.

The canonical name of the server serving the request.

This is the virtual server IPv4 address in the system, if load balancing, content switching, and/or cache redirection is used.

This is the virtual server IPv6 address in the system, if load balancing, content switching, and/or cache redirection is used.

For example, if you define the log format as %+{user-agent}i, and if the user agent value is Citrix NetScaler system Web Client, then the information is logged as Citrix NetScaler system +Web+Client. An alternative is to use double quotation marks. For example, “%{user-agent}i” logs it as “Citrix NetScaler system Web Client.” Do not use the <Esc> key on strings from %.. .r, %. . .i and, %. . .o. This complies with the requirements of the Common Log Format. Note that clients can insert control characters into the log. Therefore, you should take care when working with raw log files.
