WordPress Static file acceleration, integrated CDN

A recent company's online store project, with the bottom of the wordpress+woocommerce, a lot of custom additional features are developed by me, the final deployment of the plan to integrate the CDN, the static content is diverted to the Edge server, wordpress only processing data logic, That is, just run the PHP program.

This involves how to replace the default static resource URL into a CDN URL, turned over the internet, there are already Daniel wrote a reliable plugin, this Daniel's blog address

https://dannyvankooten.com/using-a-cdn-with-wordpress/

People have already made their own projects on GitHub.

Https://github.com/dannyvankooten/wp-cdn-loader

Download plugins directly to Wp-content/plugins, unzip, activate on admin page to use

Https://github.com/dannyvankooten/wp-cdn-loader/archive/master.zip

First of all to add this line in the wp-config.php, can be used as a switch to open the CDN, another switch is in the background

Turn off the function of this plugin ~

Define (' Dvk_cdn_url ', ' http://xxxxxx.cloudfront.net ');//the plugin won ' t replace assets when Script_debug was enabled.

Once configured, refresh the page to see that all css,js,jpg,png URLs are replaced with the set values (

Http://xxxxxx.cloudfront.net

), stating that the configuration was successful!

Curiosity, studied the code written by others, a total of 2 files, the main file
