<p>The User Agent class is always available directly from the current <a class="reference internal" href="../incoming/incomingrequest.html"><span class="doc">IncomingRequest</span></a> instance.
|
|
By default, you will have a request instance in your controller that you can retrieve the
|
|
User Agent class from:</p>

<h3><a class="toc-backref" href="#id3">User Agent Definitions</a><a class="headerlink" href="#user-agent-definitions" title="Permalink to this headline">¶</a></h3>
|
|
<p>The user agent name definitions are located in a config file located at:
|
|
<strong>app/Config/UserAgents.php</strong>. You may add items to the various

user agent arrays if needed.</p>

|
|
<p>When the User Agent class is initialized it will attempt to determine
|
|
whether the user agent browsing your site is a web browser, a mobile
|
|
device, or a robot. It will also gather the platform information if it
|
|
is available:</p>
