[${now}] ${ip_remote}: ${request} (${status})
This module implements a flexible mechanism for logging requests made to the server, using a user-specified format.
The format in which the request will be logged is defined by a string. This string is used to log each request to the log. It can contain both literal characters and a set of variables. All the literal characters will be copied to the log. The following variables will be evaluated right before writing each log entry:
Variable | Example | Description |
---|---|---|
${ip_remote} |
74.125.67.100 |
Remote IP-address |
${ip_local} |
10.0.0.1 |

/file.txt |

The templating subsystem provides slicing support in pretty much the same way that the Python strings do, allowing to use specific portions of any of these substitution macros. You can read more about this on the Template Subsystem section of the documentation.
For instance, the following format string:
[${now}] ${ip_remote}: ${request} (${status})
would generate this entry in the log:
[08/Apr/2009:12:02:11 +0200] 74.125.67.100: /file.txt (200)
