When you initially setup LiteMage and get everything right, you should see “X-Litespeed-Cache:miss” for the first time visit page, then if you refresh the page, you should see “X-LiteSpeed-Cache: hit,litemage”. All visitors should see cache hit for that URL.

How about if I have many URLs and want all pages served from cache instead of cache miss? You can setup crawler to warm-up the cache for your store. After warm up, all URLs should be served from cache.

But I may still see cache miss sometime later, which possibly because cache expired through “public TTL” and Magento will need to run warm up again. On the other hand, you don't want the warmup running at the back end all time since it will use CPU resources and push server load to be higher. If warmup running time = X, you can set Warmup interval = 3X, public TTL = 4X.

There could be another reason that if you have set to clean cache storage directory regularly, you will see cache miss after cache files being removed.
