Accesslog
=========
---------------------
Module: mod_accesslog
---------------------
.. meta::
:keywords: lighttpd, accesslog, CLF
.. contents:: Table of Contents
Description
===========
CLF like by default, flexible like apache
Options
=======
accesslog.use-syslog
send the accesslog to syslog
Default: disabled
accesslog.filename
name of the file where the accesslog should be written to if syslog
is not used.
if the name starts with a '|' the rest of the name is taken
as the name of a process which will be spawned spawn and will get the
output
e.g.: ::
accesslog.filename = "/var/log/lighttpd.log"
$HTTP["host"] == "mail.example.org" {
accesslog.filename = "|/usr/bin/cronolog"
}
if you have multiple workers on 1.4.x (now, the current version)
and want all access logs to be written writed (without that, only one worker will write logs), use
the accesslog.filename = "\|/usr/sbin/cronolog.. (as a temporary solution)
Default: disabled
accesslog.format
the format of the logfile
====== ================================
Option Description
====== ================================
%% a percent sign
%h name or address of remote-host
%l ident name (not supported)
%u authenticated user
%t timestamp for the request-start
%r request-line
%s status code
%b bytes sent for the body
%i HTTP-header field
%a remote address
%A local address
%B same as %b
%C cookie field (not supported)
%D time used in ms (not supported)
%e environment (not supported)
%f physical filename
%H request protocol (HTTP/1.0, ...)
%m request method (GET, POST, ...)
%n (not supported)
%o `response header`_
%p server port
%P (not supported)
%q query string
%T time used in seconds
%U request URL
%v server-name
%V HTTP request host name
%X connection status
%I bytes incomming
%O bytes outgoing
====== ================================
If %s is written %>s or %<s the < and the > are ignored. They are support
for compat with apache.
%i and %o expect the name of the field which should be written in curly brackets.
e.g.: ::
accesslog.format = "%h %l %u %t \"%r\" %b %>s \"%{User-Agent}i\" \"%{Referer}i\""
Default: CLF compatible output. Format from 1.4.13 source: ``"%h %V %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""`` The difference between Apache's CLF is the second field changes from ``%l`` to ``%V``.
Response Header
---------------
The accesslog module provides a special way to log content from the
application in a accesslog file. It can be used to log the session id into a
logfile.
If you want to log it into the accesslog just specify the field-name within
a %{...}o like ::
accesslog.format = "%h %l %u %t \"%r\" %b %>s \"%{User-Agent}i\" \"%{Referer}i\" \"%{X-LIGHTTPD-SID}o\""
The prefix ``X-LIGHTTPD-`` is special as every response header starting with
this prefix is assumed to be special for lighttpd and won't be sent out
to the client.
An example the use this functionality is provided below: ::
<?php
session_start();
header("X-LIGHTTPD-SID: ".session_id());
?>
