| + | ===== Cache Policy Settings ===== | ||
| + | |||
| + | The default LiteSpeed Cache settings work well with most caching scenarios. If you're configuring a shared hosting environment, don't change any of the **Server Level** default cache policy settings. 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 | ||
| + | Cache Stale Age (seconds)Not Set | ||
| + | Cache Request with Query String:Not Set | ||
| + | Cache Request with Cookie:Not Set | ||
| + | Cache Response with Cookie:Not Set | ||
| + | Ignore Request Cache-Control:Not Set | ||
| + | Ignore Response Cache-Control:Not Set | ||
| + | Enable Private Cache:Not Set | ||
| + | Check Private Cache:Not Set | ||
| + | Private Cache Expire Time (seconds):Not Set | ||
| + | |||
| + | Add the following Apache style configuration directive to ''.htaccess'' file of a specific WordPress installation to enable cache lookup. | ||
| <IfModule LiteSpeed> | <IfModule LiteSpeed> | ||
| CacheLookup public on | CacheLookup public on | ||
| </IfModule> | </IfModule> | ||

| - | Perform a web server graceful restart. | ||
| - | |||
| - | **Note:** Shared hosting providers can selectively enable LSCache by setting **Check Public Cache** to "No" at the server level (Configuration>>Server>>Cache>>Cache Policy) and then adding this directive in the .htaccess file of a specific WordPress installation. This will have the effect of turning on LSCache for only this site, allowing you to choose which sites have caching enabled. | ||
| - | ==== Advanced Cache Configuration ==== | + | **Note:** |
| + | * **"Enable Public Cache"** should always be "Not Set" or "No" unless you want to enable cache globally, which is definitely not recommended. | ||
| + | * **Check Public Cache** better set to "Not Set" but should never be "No" otherwise it will turn off the cache lookup and LScache won't work. | ||
