Edge Side Includes or ESI is a small markup language for edge level dynamic web content ESI is implemented by some content delivery networks, such as Akamai, and by some caching proxy servers such as Varnish, Squid and Mongrel . A dockerized version of Akamai’s Edge Side Includes Test Server (ETS). – akamai /esi-test-server-docker.

Edge Architecture Specification This document defines the Edge Architecture, which extends the web infrastructure through the use of HTTP akamaai – intermediaries that act on behalf of an origin server.
From Wikipedia, the free encyclopedia. The goal of ESI is to solve the problem of web infrastructure scaling and content publishing. The main alternatives to ESI are: Tom Leighton Rick M.
akamqi Alternatively the whole page with the ESI tags may be cached, and only the ESI requests may be made to the origin server. By assembling dynamic pages from individual ajamai fragments only non- cacheable or expired fragments need to be fetched from the origin location, thereby lowering eis need to retrieve complete pages.
This sample shows an incorrect input error, where the type value defines the type of problem, and the instance may be useful if you need to communicate about the problem with your Akamai support representative: ESI provides a mechanism for managing online content transparently across application server solutions, content management systems and content delivery networks.
This specification defines the ESI Invalidation Protocol that allows for tight coherence between origin serves and surrogates also known as “Reverse Proxies”. This operation provides a debugging report on the ESI code of your source page and all pages that the source page references.
Getting started To configure this API for the first time: To diagnose many common problems Akamai customers experience when delivering content to their end users, see also The Diagnostic Tools API.

How does it work? The W3C has acknowledged receipt, but has not accepted the proposal. This creates a problem for caching systems. You can use it to debug production websites or test origin sites.
