<p>If you blog are using CloudFront on the main WordPress domain (e.g. www.example.com), and you want to cache HTML page for not logged in user. You could set a long “Default TTL” for these HTML pages if the cache could invalidate automatically.</p>
<h4>Invalidation behaviors</h4>
<ul>
<li>Invalidate the whole cache when a new post published</li>
<li>Invalidate a post page when a post updated</li>
<li>Invalidate a post page if have any comment has changed on that page</li>
<li>Each invalidation has a minimum interval of 10 minutes</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 5.4+</li>
<li>WordPress 4.4+</li>
<li>A CloudFront account and AWS Access Key and Secret Key to access <a href="https://tlo.xyz/create-cloudfront-distribution-for-wordpress/" rel="nofollow ugc">CloudFront distribution</a>.</li>
</ul>
<h4>Recommendations</h4>
<ul>
<li>Offload CSS, JS and medias file to another domain with a different distribution, because this plugin will invalidate the whole cache when updating the post.</li>
</ul>

<h3>AWS IAM Policy Example</h3>
<pre><code>{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "cloudfront:GetDistribution",
                "cloudfront:ListInvalidations",
                "cloudfront:GetStreamingDistribution",
                "cloudfront:GetDistributionConfig",
                "cloudfront:GetInvalidation",
                "cloudfront:CreateInvalidation"
            ],
            "Effect": "Allow",
            "Resource": "*"
        }
    ]
}
</code></pre>
<p><strong>Note:</strong> The <code>cloudfront:GetInvalidation</code> permission is required for viewing detailed invalidation information. If this permission is not granted, the detail view feature will be disabled gracefully without affecting other plugin functionality.</p>
<h3>Adding your configuration through env vars</h3>
<p>The plugin can be configured by defining the following variables:</p>
<ul>
<li><code>AWS_ACCESS_KEY_ID</code></li>
<li><code>AWS_SECRET_ACCESS_KEY</code></li>
<li><code>C3_DISTRIBUTION_ID</code></li>

<pre><code>php
define( 'AWS_ACCESS_KEY_ID', '' );
define( 'AWS_SECRET_ACCESS_KEY', '' );
define( 'C3_DISTRIBUTION_ID', '' );
</code></pre>
