If you subscribe to the Sucuri Security website, you do not need to set the cache-level from server-side. Because by default the cache-level is already Enabled.
Some files that are cached by default include :
- js
- css
- png
- jpg
- swf
- jpeg
- svg
- gif
- ico
- txt
- mp4
- mp3
- woff
- ttf
- thumb
You can request to our support team the cache level needed for your website needs. Whether it's :
- Minimal cache (several minutes)
- Site caching (Site headers website)
- Disable cache
For the extensions mentioned above, it will remain cached even if it is set to Disable cache.
