<p>The Docket Cache is a persistent WordPress Object Cache solution designed to store data as plain PHP code. It offers an efficient alternative for users who are unable to utilize Redis or Memcached servers.</p>
<p>Unlike conventional approaches that rely on <a href="https://www.php.net/manual/en/function.serialize.php" rel="nofollow ugc">serializing</a> and <a href="https://www.php.net/manual/en/function.unserialize.php" rel="nofollow ugc">unserializing</a> PHP objects to store them into flat files, this plugin transforms objects into plain PHP code. This method significantly enhances data retrieval speed and overall performance, especially when paired with Zend OPcache.</p>
<p>For more information, please refer to the documentation on <a href="https://docs.docketcache.com/resources/caching-in-wordpress" rel="nofollow ugc">Caching In WordPress</a>.</p>
<h3>Why use this plugin?</h3>
<p>When it comes to reliable persistent Object Cache in WordPress, <a href="https://redis.io/" rel="nofollow ugc">Redis</a> or <a href="https://memcached.org/" rel="nofollow ugc">Memcached</a> comes on top. However, those solutions require knowledge of server and rarely available at low cost or shared hosting servers.</p>
<p>The only viable solution is to store object caches in files. In WordPress, exporting PHP objects is not easy. Most plugins implementing file-based caching rely on serializing and unserializing objects to store and retrieve data.</p>
<p>Docket Cache takes a better approach by turning the object cache into plain PHP code. This solution is faster since WordPress can use the cache directly without running other operations.</p>

<p>The plugin solves two problems:</p>
<ol>
<li>When WordPress detects that FastCGI PHP SAPI is in use, it<br />
<a href="http://blog.sjinks.pro/wordpress/510-wordpress-fastcgi-and-301-redirect/" rel="nofollow ugc">disregards the redirect status code</a><br />
passed to <code>wp_redirect</code>. Thus, all 301 redrects become 302 redirects<br />
which may not be good for SEO. The plugin overrides <code>wp_redirect</code> when it detects<br />
that nginx is used.</li>
<li>When WordPress detects that <code>mod_rewrite</code> is not loaded (which is the case for nginx as<br />
it does not load any Apache modules) it falls back to <a href="https://codex.wordpress.org/Using_Permalinks#PATHINFO:_.22Almost_Pretty.22" rel="nofollow ugc">PATHINFO permalinks</a><br />
in Permalink Settings page. nginx itself has built-in support for URL rewriting and does not need<br />
PATHINFO permalinks. Thus, when the plugin detects that nginx is used, it makes WordPress think<br />
that <code>mod_rewrite</code> is loaded and it is OK to use pretty permalinks.</li>
</ol>
<p>The plugin does not require any configuration. It just does its work.<br />
You won’t notice it — install and forget.</p>
<p><strong>WARNING:</strong> nginx must be configured properly to support permalinks.</p>
<h3>nginx Configuration</h3>
<p><strong>nginx 0.7.32 and higher:</strong></p>
<pre><code>server {
    server_name mysite.com;

    root /path/to/blog;

    index index.php;

    error_page 404 = @wordpress;
    log_not_found off;

    location ^~ /files/ {
        rewrite /files/(.+) /wp-includes/ms-files.php?file=$1 last;
    }

    location @wordpress {
        fastcgi_pass ...;
        fastcgi_param SCRIPT_FILENAME $document_root/index.php;
        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_NAME /index.php;
    }

    location ~ \.php$ {
        try_files $uri @wordpress;
        fastcgi_index index.php;
        fastcgi_pass ...;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
    }

    location ^~ /blogs.dir/ {
        internal;
        root /path/to/blog/wp-content;
    }
}
</code></pre>
<p><strong>Older versions:</strong></p>
<pre><code>server {
    server_name mysite.com;

    root /path/to/blog;

    index index.php;

    log_not_found off;
    error_page 404 = @wordpress;

    location ^~ /files/ {
        rewrite /files/(.+) /wp-includes/ms-files.php?file=$1 last;
    }

    location @wordpress {
        fastcgi_pass ...;
        fastcgi_param SCRIPT_FILENAME $document_root/index.php;
        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_NAME /index.php;
    }

    location ~ \.php$ {
        if (!-e $request_filename) {
            rewrite ^(.+)$ /index.php break;
            break;
        }

        fastcgi_index index.php;
        fastcgi_pass ...;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;
    }

    location ^~ /blogs.dir/ {
        internal;
        root /path/to/blog/wp-content;
    }
}
</code></pre>
<p>Of course, do not forget to replace <code>...</code> in <code>fastcgi_pass</code> with the address/socket<br />
php-cgi is listening on and replace /path/to/blog with the actual path.</p>
<p>Also please note that the path in <code>SCRIPT_NAME</code> should be relative to the <code>DOCUMENT_ROOT</code> (<code>root</code> directive).<br />
Thus, if your WordPress blog resides in <code>http://example.com/blog/</code>, <code>root</code> is set to <code>/path.to/example.com</code>,<br />
    SCRIPT_NAME in <code>location @wordpress</code> will be <code>/blog/index.php</code>.</p>
<p><strong><a href="http://blog.sjinks.pro/wordpress/874-wpms-nginx-accel-redirect/" rel="nofollow ugc">Multi-Site Configuration</a>:</strong> the above configs work perfectly with WordPress MultiSite. To make downloads faster, consider adding this line to <code>wp-config.php</code>:</p>
<pre><code>define('WPMU_ACCEL_REDIRECT', true);
</code></pre>
