<h1>Web Proxy</h1>
<p>
Squid is a web proxy server. It makes web requests in behalf of the client, and 
inspecting the returned and optionally caches that content so that the next time 
a client request is made, the content can be served from local disk. This can make 
web surfing faster. Squid can also forward its requests on to a content filter, 
such as DansGuardian.
</p>
<p>
This page lets you modify the authentication scheme of squid.
</p>

<h2>Status</h2>
<form action="" method="POST">
<dt>squid is: <? io.write( service.status ) ?></dt>
<dd><input class="submit" type="submit" name="srvcmd" value="start" <? io.write( srv1fill ) ?>>
<input class="submit" type="submit" name="srvcmd" value="stop" <? io.write( srv2fill ) ?>>
<input class="submit" type="submit" name="srvcmd" value="restart" <? io.write( srv2fill ) ?>></dd>
</form>

<p>
<pre style="color: #ff2020;"><? io.write( service.message ) ?></pre>
</p>

<p>
This process runs as a service. When you make and save changes, the configuration 
files for the service are changed. However, the changes will not be <i>applied</i> 
until you restart the service.
