<h3>Summary</h3>
|
||
|
||
<p>This module provides for flexible logging of client
|
||
requests. Logs are written in a customizable format, and may be
|
||
written directly to a file, or to an external program.
|
||
Conditional logging is provided so that individual requests may
|
||
be included or excluded from the logs based on characteristics
|
||
of the request.</p>
|
||
|
||
<p>Three directives are provided by this module:
|
||
<code class="directive"><a href="#transferlog">TransferLog</a></code> to create
|
||
a log file, <code class="directive"><a href="#logformat">LogFormat</a></code>
|
||
to set a custom format, and <code class="directive"><a href="#customlog">CustomLog</a></code> to define a log file and format in one
|
||
step. The <code class="directive">TransferLog</code> and <code class="directive">CustomLog</code> directives can be used multiple times in each
|
||
server to cause each request to be logged to multiple files.</p>

|

<p>The format argument to the <code class="directive"><a href="#logformat">LogFormat</a></code> and <code class="directive"><a href="#customlog">CustomLog</a></code> directives is a string. This string is
|
||
used to log each request to the log file. It can contain literal
|
||
characters copied into the log files and the C-style control
|
||
characters "\n" and "\t" to represent new-lines and tabs.
|
||
Literal quotes and back-slashes should be escaped with
|
||
back-slashes.</p>
|
||
|
||
<p>The characteristics of the request itself are logged by
|
||
placing "<code>%</code>" directives in the format string, which are
|
||
replaced in the log file by the values as follows:</p>

<h3><a name="modifiers" id="modifiers">Modifiers</a></h3>
|
||
|
||
<p>Particular items can be restricted to print only for
|
||
responses with specific HTTP status codes by placing a
|
||
comma-separated list of status codes immediately following the
|
||
"%". For example, <code>"%400,501{User-agent}i"</code> logs
|
||
<code>User-agent</code> on 400 errors and 501 errors only. For
|
||
other status codes, the literal string <code>"-"</code> will be
|
||
logged. The status code list may be preceded by a
|
||
"<code>!</code>" to indicate negation:
|
||
<code>"%!200,304,302{Referer}i"</code> logs <code>Referer</code>
|
||
on all requests that do <em>not</em> return one of the three
|
||
specified codes.</p>
|
||
|
||
<p>The modifiers "<" and ">" can be used for requests that
|
||
have been internally redirected to choose whether the original
|
||
or final (respectively) request should be consulted. By
|
||
default, the <code>%</code> directives <code>%s, %U, %T,
|
||
%D,</code> and <code>%r</code> look at the original request
|
||
while all others look at the final request. So for example,
|
||
<code>%>s</code> can be used to record the final status of
|
||
the request and <code>%<u</code> can be used to record the
|
||
original authenticated user on a request that is internally
|
||
redirected to an unauthenticated resource.</p>
|
||
|
||
|
||
|
||
<h3><a name="format-notes" id="format-notes">Some Notes</a></h3>
|
||
|
||
<p>For security reasons, starting with version 2.0.46,
|
||
non-printable and other special characters in <code>%r</code>,
|
||
<code>%i</code> and <code>%o</code> are escaped using
|
||
<code>\x<var>hh</var></code> sequences, where <var>hh</var>
|
||
stands for the hexadecimal representation of the raw
|
||
byte. Exceptions from this rule are <code>"</code> and
|
||
<code>\</code>, which are escaped by prepending a backslash, and
|
||
all whitespace characters, which are written in their C-style
|
||
notation (<code>\n</code>, <code>\t</code>, etc). In versions
|
||
prior to 2.0.46, no escaping was performed on these strings so
|
||
you had to be quite careful when dealing with raw log files.</p>
|
||
|
||
<p>In httpd 2.0, unlike 1.3, the <code>%b</code> and
|
||
<code>%B</code> format strings do not represent the number of
|
||
bytes sent to the client, but simply the size in bytes of the
|
||
HTTP response (which will differ, for instance, if the
|
||
connection is aborted, or if SSL is used). The <code>%O</code>
|
||
format provided by <code class="module"><a href="../mod/mod_logio.html">mod_logio</a></code> will log the
|
||
actual number of bytes sent over the network.</p>
|
||
|
||
<p>Note: <code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> is implemented as a
|
||
quick-handler and not as a standard handler. Therefore, the
|
||
<code>%R</code> format string will not return any handler
|
||
information when content caching is involved.</p>

<p>The second argument specifies what will be written to the
|
||
log file. It can specify either a <var>nickname</var> defined by
|
||
a previous <code class="directive"><a href="#logformat">LogFormat</a></code>
|
||
directive, or it can be an explicit <var>format</var> string as
|
||
described in the <a href="#formats">log formats</a> section.</p>
|
||
|
||
<p>For example, the following two sets of directives have
|
||
exactly the same effect:</p>
|
||
|
||
<div class="example"><p><code>
|
||
# CustomLog with format nickname<br />
|
||
LogFormat "%h %l %u %t \"%r\" %>s %b" common<br />
|
||
CustomLog logs/access_log common<br />
|
||
<br />
|
||
# CustomLog with explicit format string<br />
|
||
CustomLog logs/access_log "%h %l %u %t \"%r\" %>s %b"
|
||
</code></p></div>
|
||
|
||
<p>The third argument is optional and controls whether or
|
||
not to log a particular request based on the
|
||
presence or absence of a particular variable in the server
|
||
environment. If the specified <a href="../env.html">environment
|
||
variable</a> is set for the request (or is not set, in the case
|
||
of a '<code>env=!<var>name</var></code>' clause), then the
|
||
request will be logged.</p>
|
||
|
||
<p>Environment variables can be set on a per-request
|
||
basis using the <code class="module"><a href="../mod/mod_setenvif.html">mod_setenvif</a></code>
|
||
and/or <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> modules. For
|
||
example, if you want to record requests for all GIF
|
||
images on your server in a separate logfile but not in your main
|
||
log, you can use:</p>
|
||
|
||
<div class="example"><p><code>
|
||
SetEnvIf Request_URI \.gif$ gif-image<br />
|
||
CustomLog gif-requests.log common env=gif-image<br />
|
||
CustomLog nongif-requests.log common env=!gif-image
|
||
</code></p></div>
|
||
|
||
<p>Or, to reproduce the behavior of the old RefererIgnore
|
||
directive, you might use the following:</p>
|
||
|
||
<div class="example"><p><code>
|
||
SetEnvIf Referer example\.com localreferer<br />
|
||
CustomLog referer.log referer env=!localreferer
|
||
</code></p></div>
|
||
|
||
</div>

||

|
||
<p>This directive specifies the format of the access log
|
||
file.</p>
|
||
|
||
<p>The <code class="directive">LogFormat</code> directive can take one of two
|
||
forms. In the first form, where only one argument is specified,
|
||
this directive sets the log format which will be used by logs
|
||
specified in subsequent <code class="directive">TransferLog</code>
|
||
directives. The single argument can specify an explicit
|
||
<var>format</var> as discussed in the <a href="#formats">custom log
|
||
formats</a> section above. Alternatively, it can use a
|
||
<var>nickname</var> to refer to a log format defined in a
|
||
previous <code class="directive">LogFormat</code> directive as described
|
||
below.</p>
|
||
|
||
<p>The second form of the <code class="directive">LogFormat</code>
|
||
directive associates an explicit <var>format</var> with a
|
||
<var>nickname</var>. This <var>nickname</var> can then be used in
|
||
subsequent <code class="directive">LogFormat</code> or
|
||
<code class="directive"><a href="#customlog">CustomLog</a></code> directives
|
||
rather than repeating the entire format string. A
|
||
<code class="directive">LogFormat</code> directive that defines a nickname
|
||
<strong>does nothing else</strong> -- that is, it <em>only</em>
|
||
defines the nickname, it doesn't actually apply the format and make
|
||
it the default. Therefore, it will not affect subsequent
|
||
<code class="directive"><a href="#transferlog">TransferLog</a></code> directives.
|
||
In addition, <code class="directive">LogFormat</code> cannot use one nickname
|
||
to define another nickname. Note that the nickname should not contain
|
||
percent signs (<code>%</code>).</p>
|
||
|
||
<div class="example"><h3>Example</h3><p><code>
|
||
LogFormat "%v %h %l %u %t \"%r\" %>s %b" vhost_common
|
||
</code></p></div>
|
||
|
||
</div>
|
||
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
|
||
<div class="directive-section"><h2><a name="TransferLog" id="TransferLog">TransferLog</a> <a name="transferlog" id="transferlog">Directive</a></h2>
|

<table class="directive">

</table>
|
||
<p>This directive has exactly the same arguments and effect as
|
||
the <code class="directive"><a href="#customlog">CustomLog</a></code>
|
||
directive, with the exception that it does not allow the log format
|
||
to be specified explicitly or for conditional logging of requests.
|
||
Instead, the log format is determined by the most recently specified
|
||
<code class="directive"><a href="#logformat">LogFormat</a></code> directive
|
||
which does not define a nickname. Common Log Format is used if no
|
||
other format has been specified.</p>
|
||
|
||
<div class="example"><h3>Example</h3><p><code>
|
||
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-agent}i\""<br />
