The result of this query is written to a cache; the next requests will be served from that cache. Add &DPL_refresh=yes to the URL to enforce a cache update.

Note that each scrolled page is separately cached. Once you refresh the cache, all pages of former scrolling actions are removed.

Try the following:

1. load the page and click on the small "refresh" link below the table
2. remove the "&DPL_refresh=yes" part AND the "&DPL_offset=0" part in the URL of your browser and reload the page
3. reload again
4. scroll to the next page
5. scroll back, i.e. click on "1..10"
6. scroll forward (11..20)
7. scroll forward (21..30)
8. click on the small "refresh" link below the table
9. remove the "&DPL_refresh=yes" part in the URL of your browser and reload the page
10. scroll back (11..20)
11. scroll forward (21..30)

• In step 1 there is no message - the cache has silently been created, cache pages of older scroll events have been removed
• In steps 2,3,5,6,11 you should see a small note which proves that the result comes from the cache. Watch the "age2 indicator!
• In the other steps (2,4,7,8,9,10) you should see a note that the cache has been created or re-built.

Note the path descriptor of the dplcache which arranges all scrolled result pages withn a subdirectory of the cache.
