<h3>Summary</h3>
<p>This module is designed for the use in test suites and large
networks which have to deal with different httpd versions and
different configurations. It provides a new container -- <code class="directive"><a href="#ifversion"><IfVersion></a></code>, which
allows a flexible version checking including numeric comparisons and
regular expressions.</p>
<div class="example"><h3>Examples</h3><pre class="prettyprint lang-config">
<IfVersion 2.4.2>
# current httpd version is exactly 2.4.2
</IfVersion>
<IfVersion >= 2.5>
# use really new features :-)
</IfVersion>
</pre>
</div>
<p>See below for further possibilities.</p>
</div>

<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="IfVersion" id="IfVersion"><IfVersion></a> <a name="ifversion" id="ifversion">Directive</a></h2>
<table class="directive">
<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>contains version dependent configuration</td></tr>
<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code><IfVersion [[!]<var>operator</var>] <var>version</var>> ...
</IfVersion></code></td></tr>
<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host, directory, .htaccess</td></tr>
<tr><th><a href="directive-dict.html#Override">Override:</a></th><td>All</td></tr>
<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr>
<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_version</td></tr>
</table>
<p>The <code class="directive"><IfVersion></code> section encloses
configuration directives which are executed only if the
<code class="program"><a href="../programs/httpd.html">httpd</a></code> version
matches the desired criteria. For normal (numeric) comparisons the
<var>version</var> argument has the format
<code><var>major</var>[.<var>minor</var>[.<var>patch</var>]]</code>, e.g.
<code>2.1.0</code> or <code>2.2</code>. <var>minor</var> and
<var>patch</var> are optional. If these numbers are omitted, they are
assumed to be zero. The following numerical <var>operator</var>s are
possible:</p>
<table class="bordered"><tr class="header"><th><var>operator</var></th><th>description</th></tr>
<tr><td><code>=</code> or <code>==</code></td>
<td>httpd version is equal</td></tr>
<tr class="odd"><td><code>></code></td>
<td>httpd version is greater than</td></tr>
<tr><td><code>>=</code></td>
<td>httpd version is greater or equal</td></tr>
<tr class="odd"><td><code><</code></td>
<td>httpd version is less than</td></tr>
<tr><td><code><=</code></td>
<td>httpd version is less or equal</td></tr>
</table>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">
<IfVersion >= 2.3>
# this happens only in versions greater or
# equal 2.3.0.
</IfVersion>
</pre>
</div>
<p>Besides the numerical comparison it is possible to match a
<a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expression</a>
against the httpd version. There are two ways to write it:</p>
<table class="bordered"><tr class="header"><th><var>operator</var></th><th>description</th></tr>
<tr><td><code>=</code> or <code>==</code></td>
<td><var>version</var> has the form
<code>/<var>regex</var>/</code></td></tr>
<tr class="odd"><td><code>~</code></td>
<td><var>version</var> has the form
<code><var>regex</var></code></td></tr>
</table>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">
<IfVersion = /^2.4.[01234]$/>
# e.g. workaround for buggy versions
</IfVersion>
</pre>
</div>
<p>In order to reverse the meaning, all operators can be preceded by an
exclamation mark (<code>!</code>):</p>
<pre class="prettyprint lang-config">
<IfVersion !~ ^2.4.[01234]$>
# not for those versions
</IfVersion>
</pre>
<p>If the <var>operator</var> is omitted, it is assumed to be
<code>=</code>.</p>
