Development

• Caching

  • ESI = “edge side includes”. Created by Akamai and used in their “cloud”. ESI pushes out simple conditional rendering tasks to the “edge”, which is tpyically a cache server cluster.
  • Using ESI can help reduce the number of requests which make it through the cache tier to the Zope tier.
  • Down sides: requires extensive “buy in” during development; difficult to test during development and in production.
  • Zope Corporation sponsored integration of ESI into Squid 3.
