Function groups implemented in JotCache can be described in following way :

1. main operation mode :
   1. which cache storage have to be used - e.g. file system, memcached, redis
   2. where to perform caching - selection of server cache (most used mode) or browser caching (very special case)
   3. one site / multisite operation
   4. one cache lifetime (expiration time) or many different lifetime settings for chosen groups of pages
   5. global rule for page URL processing - include or exclude chosen URLs from page caching
2. exclusions from caching :
   1. of entire page based on page URL
   2. of chosen template positions for modules which have to be excluded
   3. based on visitor access (bots, crawlers, user browser agent)
3. cache split - using different spaces in cache storage based on :
   1. user browser agent
   2. page cookies
   3. session variables
4. recache of site pages - manually in JotCache component or automatically using server cron job
5. cache clean - removing expired cached pages from cache storage to keep memory space in reasonable size
6. setup tools - different debugging , logging and marking functions to support administrator setup
