</p>
<p>The LiteSpeed Web Cache Manager allows the cPanel end-user to...</p>
<ul>
  <li>Enable/Disable supported LiteSpeed Cache plugins on owned sites.</li>
  <li>Flush LSCache for all owned sites.</li>
  <li>
    Flag and unflag owned sites as excluded from WHM Mass Enable/Disable Cache
    operations.
  </li>
  <li>
    (When enabled through "cPanel Settings" in WHM plugin) Generate EC SSL
    certificates for owned domains, improving SSL performance with supporting
    browsers.
  </li>
</ul>
<h2>Hosting Provider Benefits</h2>
<p>
  The LiteSpeed Web Cache Manager allows hosting providers to...
</p>
<ul>
  <li>Provide a convenient cache management tool for end-users.</li>
  <li>
    Customize the plugin landing page to...
    <ul>
      <li>Advertise features or specialized services.</li>
