Web Cache Web Server Configuration - Plesk Single Site

Create a file named “lscache.conf” with the following content in directory /etc/httpd/conf.d/:

<IfModule Litespeed>
  CacheRoot /var/www/vhosts/lscache/
</IfModule>

Note: It is recommended to set the server level Cache Root to /var/www/vhosts/lscache/ or a disk partition with enough space.

LiteSpeed Cache default settings work well with most caching scenarios. For shared hosting environment, please don't change any of the Server Level default cache policy settings and leave them as “Not Set”.

Cache Policy:
Enable Public Cache:Not Set
Check Public Cache:Not Set
Max Object Size:Not Set
Cache Expire Time (seconds):Not Set
