Features
There are four main features in ESI:
- inclusion of page fragments, as illustrated above;
- variables which can be set from cookies or HTTP headers and then used in other ESI statements or written into markup;
- conditions so that different markup can be used based on variables, for example if a cookie is set or not;
- error handling, so that a failover can be used if an origin server is unavailable.

Famous quotes containing the word features:
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
“All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!”
—Herman Melville (1819–1891)
