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:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“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)
“It is a tribute to the peculiar horror of contemporary life that it makes the worst features of earlier times—the stupefaction of the masses, the obsessed and driven lives of the bourgeoisie—seem attractive by comparison.”
—Christopher Lasch (b. 1932)
