Comment Saver temporarily stores the content of comments in a browser cookie 
just in case something goes wrong while submitting the comment. For example, 
if the user forgot to include their name and email address and those fields are 
required, the comment may be lost on some browsers. When the user returns to 
the comment form, Comment Saver will automatically populate the comment box if 
the cookie is still set. It will remove the temporary cookie once the comment 
has been successfully submitted, or after one hour.

WordPress core does not use PHP sessions, but sometimes they are required by your use-case, a plugin or theme.
This plugin implements PHP’s native session handlers, backed by the WordPress database. This allows plugins, themes, and custom code to safely use PHP <code>$_SESSION</code>s in a distributed environment where PHP’s default tempfile storage just won’t work.
Note that primary development is on GitHub if you would like to contribute:
https://github.com/pantheon-systems/wp-native-php-sessions
<h3>Configuration</h3>
By default the session lifetime is set to 0, which is until the browser is closed.
To override this use the <code>pantheon_session_expiration</code> filter before the Native PHP Sessions plugin is loaded. For example a small Must-use plugin (a.k.a. mu-plugin) could contain:
<pre><code><?php
function my_session_expiration_override() {
 return 60*60*4; // 4 hours
}
add_filter( 'pantheon_session_expiration', 'my_session_expiration_override' );<h3>CLI Commands</h3>
</code></pre>
wp pantheon session add-index
Added in 1.4.0. This command should be run if your installation of the plugin occurred before the addition of the primary ID key to the session table in version 1.2.2. You will be automatically notified when you visit any admin page if this is the case. If there’s no message, your version is good to go. Note that this command is non-destructive, a new table will be created and the existing one preserved in a backup state until you have verified that the upgrade is functioning as expected.
wp pantheon session primary-key-finalize
Added in 1.4.0. If you have run the <code>add-index</code> command and have verified that the new table is functioning correctly, running the <code>primary-key-finalize</code> command will perform a database cleanup and remove the backup table.
wp pantheon session primary-key-revert
Added in 1.4.0. If you have run the <code>add-index</code> command and something unexpected has occurred, just run the <code>primary-key-revert</code> command and the backup table will immediately be returned to being the active table.
<h4>WordPress Multisite</h4>
As of 1.4.2 the <code>add-index</code>, <code>primary-key-add</code> and <code>primary-key-revert</code> commands are fully multisite compatible.
<h3>Contributing</h3>
See <a href="https://github.com/pantheon-systems/wp-native-php-sessions/blob/main/CONTRIBUTING.md" rel="nofollow ugc">CONTRIBUTING.md</a> for information on contributing.
<h3>Troubleshooting</h3>
If you see an error like “Fatal error: session_start(): Failed to initialize storage module:” or “Warning: ini_set(): A session is active.”, then you likely have a plugin that is starting a session before WP Native PHP Sessions is loading.
To fix, create a new file at <code>wp-content/mu-plugins/000-loader.php</code> and include the following:
<pre><code><?php
if (file_exists(WP_PLUGIN_DIR . '/wp-native-php-sessions/pantheon-sessions.php')) {
 require_once WP_PLUGIN_DIR . '/wp-native-php-sessions/pantheon-sessions.php';
}
</code></pre>
This mu-plugin will load WP Native PHP Sessions before all other plugins, while letting you still use the WordPress plugin updater to keep the plugin up-to-date.

Native PHP Sessions

I did not have high hopes for this, looking for plugins to resolve the issue my site was having in Site Health and figured I might as well try  this after running across it on Google. I installed it, and it fixed loopback requests and API issues in Site Health. I am very impressed! 

Wow! This plugin works great!

Use native PHP sessions and stay horizontally scalable. Better living through superior technology.
