LiteSpeed Cache for WordPress (LSCWP) plugin v3.0 was in development for some time and now they have launched the much-awaited public version which includes a complete revamp of the GUI design and additions of many features. 

For availing features online services like Image Optimization, generate Critical CSS, Low-Quality Image Placeholders, QUIC.cloud CDN Cache etc., we need to generate a domain key. This process is automated. Only if you need to use QUIC.cloud CDN, you need to link the account to quic.cloud dashboard. If you are not using it and just want other features only, users can get online services as an anonymous user by just creating a domain key.

1.Login to the WordPress admin dashboard.
2. Select Litespeed cache >> General
3. On that page, there will be a box for the domain key. Click on the “Apply Domain Key” button.
4. After that, you’ll get a success message and refresh the page afterward.
5. After refreshing, the box should automatically be filled with the key and click “Save changes”
6. Once you save, click “Link to QUIC.cloud” if you wish to see all statistics and enable QUIC.cloud CDN

Something about QUIC.cloud

QUIC.cloud is the first and only content delivery network with the ability to cache dynamic WordPress pages. Using QUIC as the transfer protocol, QUIC.cloud will make your website faster and more secure than the competition. QUIC.cloud greatly reduces transmission time to all of your site’s visitors, no matter where they live. Your website is potentially located across the globe from its visitors, but with QUIC.cloud, your content is cached on servers all around the world. When a visitor requests content from your site, a copy is served from the visitor’s nearest server location. By transmitting both static and dynamic content from the closest server, instead of from the main site server, QUIC.cloud dramatically speeds up your site.

This website uses a fully integrated QUIC.cloud CDN with OpenLiteSpeed Web Server. You can see it works. But just remember QUIC.cloud CDN is still in its beta stage and is not recommended for use in heavy production environments at this time. All other LSCWP features including the online service features like Image Optimization, generate Critical CSS, Low-Quality Image Placeholders, etc. are there for quite some time and are mature for production. Feel free to use it.

It is a bit long topic to write QUIC.cloud CDN within this article about new LSCWP and will be a new post mentioning its setup, signing up to quic.cloud and all. Stay tuned for that.
