9. Servers architecture

10. Cache lookup

11. Cache refresh frequently page content updates fast appearance of new content on many pages quick response for user interaction regular changes

12. Hot news Panels Panels Everywhere edge side includes (ESI) integration panes one pane style plugin to rule all ESI

13. Hot news Just manage layouts...

14. Hot news module d.o/project/esi not used custom integration module hook for url arguments by pane type expiration by TTL pane type as ESI url part - custom TTL programmatic ESI control

15. User events comments votes counters user profile info user favorites node ratings content management

16. User events Solution - trigger PURGE/BAN of ESI, static file cache by URL Modules - Purge + Cache expiration + Rules

17. Support & deploy ESI urls and callbacks back support stubs for future features AJAX/AHAH urls and callbacks back support scripts for "smooth" static cache regeneration mistake cost multiplied - always think twice...

18. Bonuspack. Usercache all cache (user/anonym) - the same user-specific blocks by ESI pass Drupal UID with COOKIES to JS for manage "cosmetic" render manage cache exceptions

19. Bonuspack. Security - CSRF tokens - not available no proven solution may be tokens by ESI and custom script?
