esi 6.x-2.x-dev

Release notes

Add mikeytown2's hard work in the dev branch

• Support for Panel Panes
• Support for ESI (varnish), SSI (nginx), AJAX (browsers).
• AJAX can be used as a fallback if ESI doesn't work; AJAX can also be loaded from a CDN; if you don't have varnish or nginx, you can just use AJAX.
• Caching the HTML fragments in the cache_page drupal cache for faster delivery.
• Setting the TTL of the HTML fragment
• Global and per pane/block settings
• Setting the scope of the cache
  • Disabled - Do not use ESI.
  • Not Cached - Use ESI, but never cache the content.
  • Global - Content is same on every page.
  • Page - Content changes based on the URL.
  • User Role - Content changes based on the user role.
  • User Role/Page - Content changes based on the user role as well as the URL.
  • User ID - Content changes based on the UID; otherwise it is the same as global.
  • User ID/Page - Content changes based on the UID and based on the URL.
