title: Output caching in IIS doesn't work for Wordpress php files
body: <p>I enabled output caching for php files</p>
  
  <pre><code>&lt;configuration&gt;
     &lt;system.webServer&gt;
        &lt;serverRuntime frequentHitThreshold="1" frequentHitTimePeriod="00:00:30" /&gt;
        &lt;caching&gt;
           &lt;profiles&gt;
             &lt;add extension="*.php" policy="CacheForTimePeriod" kernelCachePolicy="CacheForTimePeriod" duration="00:00:59" location="Any" varyByQueryString="*" /&gt;
           &lt;/profiles&gt;
        &lt;/caching&gt;
     &lt;/system.webServer&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Caching works for PHP test file which prints time </p>
