For testing purposes, you can set up a test origin server to debug websites before deployment or modification. This operation provides a debugging report on the ESI code of your source page and all pages that the ajamai page references. This specification defines ESI 1. Hesse Tom Killalea Jonathan F. As a result, ESI enables companies to develop web applications once and choose at deployment time where the web application should be assembled – on the content management system, the application server, or the content delivery network, thus reducing aoamai, development time and deployment costs.

A debugging report on the ESI code of a source page and all included pages. Reports ESI syntax errors. The ESI system is usually a caching proxy server so it aamai have a local copy of these files which it can insert without going back to the server. The XML based ESI tags indicate to the edge-side processing agent the action that needs to be taken to complete the page’s akamaii.
