Start Your Free 60-day Trial
To install the module, you need a server with CentOs or CloudLinux 6, 7 or 8 and a valid cPanel installation.
The module can be installed with a single shell command line. You’ll need to connect in the server’s root access and run the following command to start the installation script. (more details about the installation can be found)
wget https://static.astralinternet.com/nginx/install/wsa-install && sh wsa-install stable
Once the installation process is done, your 60-day free trial will start immediately.
Like every caching system, the possibility of emptying the cache is a must. Ideally if a site could control the cache purging itself, this would make things even simpler. With this in mind, we’ve developed a plugin for WordPress that automatically clears the cache of a site when a page is modified. We have also created a PHP class which can be integrated into any sites.
WordPress Plugin
The “Cache purge for Website Accelerator” plugin will purge the server cache memory every time a page or article is modified, to prevent old pages from being displayed.
PHP Class
We’ve placed an open source PHP class on GitHub allowing any developer to quickly include the server cache purging method into their code.
Incredibly Fast! Need proof?
When something seems too good to be true, it often is. Therefore, we’ve made two identical WordPress sites so you can compare them.
A benchmark test ran with the “Siege” software showed that simply placing Nginx in front of cPanel Apache increase the number of pages the site could serve by 137% (this test was made on a WordPress site with approximately 25 plugins installed).
Now, add website caching directly in Nginx. Each site can then be tweaked for optimal caching. With previous experiences acquired through other caching systems like Varnish, we transposed our knowledge into easy-to-use options directly in cPanel. While simply activating the cache in cPanel accounts of a server, we’ve managed to increase performance by 204% on the amount of requests the site could serve.
We’ve placed two copies of the same WordPress site online. One with the Nginx cPanel (WSA) module activated and one without, so you can compare with a live scenarios.
Site without Caching

- Google Page Insight Mobile : 35%
- Google Page Insight Desktop : 83%
- GTmetrix fully load time : 4.4 s
- Pingdom load time : 2.21 s
- Chrome DevTools – DOM Content loaded : 1.99 s
Site with Caching

- Google Page Insight Mobile : 47%
- Google Page Insight Desktop : 85%
- GTmetrix fully load time : 2.9 s
- Pingdom load time : 980 ms
- Chrome DevTools – DOM Content loaded : 686 ms

100% Configurable
The module is fully configurable from the WHM GUI and can be activated from the “features” of cPanel plans. A graphical interface is also available for each of the cPanel accounts, allowing a granular configuration for each domain and subdomain.
Compatibility
The module has been verified with several thousand websites to ensure maximum compatibility. In all of our test scenarios, no websites have experienced problems after installing the module. WSA will be the best Nginx for cPanel extension you’ll ever try.

Here’s what people are saying about WSA
Faster loading without any headache!
We have bloated WordPress installation that was almost impossible to optimize, since the activation of WSA on our site, our page load time has dramatically dropped! Now I can see my site running on a server without WSA.
