Yes structure is retained, it’s just a pure domain rewrite.

hm ? I think I might be able to work out some code snippet for you

but I assume it’s unrealistic to actually have sub site named as sub1 , sub2, sub3, …etc ?

I assume it could be like

domain1.com/aaa to cdn-1.vultrcdn.com/aaa

domain1.com/bbb to cdn-1.vultrcdn.com/bbb

domain1.com/ccc to cdn-1.vultrcdn.com/ccc

domain1.com/ddd to cdn-1.vultrcdn.com/ddd

That would be awesome thank you!
sub1 and sub2 just for the sake of the example you made.

After the / it could be anything according to the website needs, for our website it’s region code for multilingual so /en, /fr etc.

So yes your assumption is still standing correct for Vultr CDN.

#!/bin/bash

site_url_list=$(wp site list --field=url --path=/path/to/site)

for site_url in $site_url_list; do
    if [ "$site_url" != "https://base_domain.com/" ]; then
        sub_path=${site_url#https://}
        sub_path=${sub_path#http://}
        sub_dir=$(echo $site_url | sed 's|https://base_domain.com/||' | sed 's|/$||')
        wp --url=$site_url litespeed-option set cdn true
        wp --url=$site_url litespeed-option set cdn-ori "//$sub_path"
        wp --url=$site_url litespeed-option set 'cdn-mapping[url][0]' "https://cdn-1.vultrcdn.com/$sub_dir"
    fi
done

okay , I spent a lot of time try to get a PHP way by conf constant define , but seems failed , however I come up an alternative with WP CLI command to set options

replace base_domain.com to your base domain and cdn-1.vultrcdn.com accordingly , as well as /path/to/site

please do make a backup of database beforehand , just in case it didn’t work out , you can revert it instead of manually go through all sites

okay , after bugged our dev to death , I finally got this

if (isset($_SERVER['REQUEST_URI']) && preg_match('#^/([^/]+)#', $_SERVER['REQUEST_URI'], $matches)) {
define( 'LITESPEED_CONF', true );
define( 'LITESPEED_CONF__CDN', true );
$cdn_url_path = explode('/', trim($_SERVER['REQUEST_URI'], '/'));
$cdn_origin_url = '//' . $_SERVER['SERVER_NAME'] . '/' . $cdn_url_path[0] . '/';
define( 'LITESPEED_CONF__CDN__ORI',[ $cdn_origin_url ] );
define('LITESPEED_CONF__CDN__MAPPING', [
    [ 'url'=> 'https://cdn.domain.com/' . $cdn_url_path[0] . '/' , 'inc_img'=>true, 'inc_css'=>true, 'inc_js'=>true, 'filetype' => ['.aac', '.css', '.eot', '.gif', '.jpeg', '.jpg', '.js', 
    '.less', '.mp3', '.mp4', '.ogg', '.otf', '.pdf', '.png', '.svg', '.ttf', '.webp', '.woff', '.woff2'] ]
]);
}

please give it a try , replace cdn.domain.com to actual one

Thank you so much, qtwrk.

I will be testing that and give you a shout whether it worked.

Thanks once again!

oh , forgot to mention , the PHP code needs to be placed in the wp-config.php , next line after <?php so it can take effect and set conf before plugins loads
