Title: Cloudflare’s Whitelist Last modified: June 20, 2019 --- # Cloudflare’s Whitelist * Resolved [merloat](https://wordpress.org/support/users/merloat/) * (@merloat) * [6 years, 11 months ago](https://wordpress.org/support/topic/cloudflares-whitelist/) * Hello everyone, * I use Cloudflare to speed up and protect my site, I use firewall rules to control who will get a JS Challenge. After using LSCache, I see there are some UK’s visitors get JS Challenges. I am wondering that they may come from LiteSpeed servers. * In order not to let LSCache work improperly, could you tell me which IP or hostname I should add to Cloudflare whitelist? * Thanks😊! - This topic was modified 6 years, 11 months ago by [merloat](https://wordpress.org/support/users/merloat/).
