### Logger: Custom

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 | Local IP-address
`${request}` | /file.txt | URL path requested
`${request_original}` | /file.txt | URL path requested before any rewrite
`${protocol}` | http | Request Protocol
`${port_server}` | 80 | Port of the server serving the request
`${query_string}` | ?bar=foo | "The query string, if exists"
`${request_first_line}` | GET / HTTP/1.0 | First line of request
`${status}` | 200 | Status of the request
`${now}` | 08/Apr/2009:12:02:11 +0200 | Time: in common log format time format
`${time_secs}` | 1239185281 | Time: seconds since Epoch
`${time_msecs}` | 18446744071655350332 | Time: milliseconds since Epoch
`${user_remote}` | guest | Remote user (authentication)
`${vserver_name}` | default | Virtual Server nick name

### Example

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)
