  3. Agenda • Server • Cache • Content • User • Developer • Bonus

  4. Requirements More than 500 000 actual pages 800 000 of registered users About 150 000 pages changed every month ALWAYS serve pages quickly

  5. Servers architecture NO Apache

  6. Servers architecture

  7. Servers architecture. Solutions Varnish: • no persistent storage • flexible ESI, cache and TTL configuration • fast memory cache

  8. Servers architecture. Solutions Nginx: • persistent file storage • hard to configure • load balancing • fast static cache

  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?
