const mixinafBedSheet::HttpRequestLogFilter

Uses LogMod to generate a server log file for all HTTP requests in the W3C Extended Log File Format.

To enable, contribute the filter to the HttpPipeline and set the log dir:

@Contribute { serviceType=HttpPipeline# }
static Void contributeHttpPipeline(OrderedConfig conf) {
  conf.addOrdered("HttpRequestLogFilter", conf.autobuild(HttpRequestLogFilter#), ["after: BedSheetFilters"])
}

@Contribute { serviceType=ApplicationDefaults# } 
static Void contributeApplicationDefaults(MappedConfig conf) {
  conf[ConfigIds.httpRequestLogDir]             = `/my/log/dir/`
  conf[ConfigIds.httpRequestLogFilenamePattern] = "afBedSheet-{YYYY-MM}.log"
}

See util::FileLogger to configure datetime patterns for your log files.

The fields property configures the format of the log records. It is a string of field names separated by a space. The following field names are supported:

• date: UTC date as DD-MM-YYYY
• time: UTC time as hh:mm:ss
• c-ip: the numeric IP address of the remote client socket
• c-port: the IP port of the remote client socket

• cs-uri-query: the encoded query of the request uri
• sc-status: the return status code
• time-taken: the time taken to process request in milliseconds
• cs(HeaderName): request header value such User-Agent

If any unknown fields are specified or not available then "-" is logged. Example log record:
