<h4>This plugin puts your W3 Total Cache configuration on auto pilot.</h4>
It’s great when you have users that don’t have access to W3 Total Cache control but still need to purge the cache.
It’s also brilliant when you have created a blog for a customer, this way they won’t even know it’s there: All cache is purged automatically.
It’s absolutely great on MultiSite installations, especially when you allow untrusted users to create a blog.
What this plugin does:
On the front end:
<ul>
<li>No more W3 Total Cache comments in the HTML output</li>
</ul>
Behind the screens:
Purge cache, whenever:
<ul>
<li>a post is updated.</li>
<li>theme is changed.</li>
<li>a widget is updated or changed from position.</li>
<li>a sidebar is updated.</li>
<li>the theme is edited in Customizer.</li>
<li>the nav menu is updated.</li>
</ul>
MultiSite, if not Super-Admin:
No more:
<ul>
<li>purge from cache button on pages and posts edit screens.</li>
<li>admin menu on the admin bar.</li>
<li>admin menu in the dashboard.</li>
<li>amin notices in the dashboard after settings change or on error.</li>
<li>admin scripts in back end.</li>
<li>admin scripts on front end.</li>
</ul>
WPMUdev Domain Mapping support
<ul>
<li>This plugin fixes a few issues when you’re combining W3TC and Domain Mapping by automatically flushing the posts on a site. This eliminates confusion. 
This plugin allows you to adjust the output of a few filters. However, the defaults should work out for everyone.</li>
</ul>
<h3>Filters</h3>
Add a greater amount of pages and posts to be flushed on several actions 
 add_filter( ‘wap_limit_flush’, ‘my_wap_limit_flush’ ) 
 function my_wap_limit_flush() { 
 $limit = 50; // Default is 20.
<pre><code> return $limit;
}
</code></pre>
Flush everything, ignoring the limit 
 add_filter( ‘wap_flush_all’, ‘__return_true’ );
