Facelets default non-hot reload in production

JSF has the ability to cache Facelets. In order to update the cache, JSF performs periodic checks of Facelets views changes. In the development stage, you may need to perform this check much often than in production. For this, you can set the javax.faces.FACELETS_REFRESH_PERIOD context parameter as shown in the following example (the value represents the number of seconds between two consecutive checks). 

5 SECONDS TIMEOUT

<context-param>

 <param-name>javax.faces.FACELETS_REFRESH_PERIOD</param-name>

 <param-value>5</param-value>

</context-param>

There are two special values:

·         -1 means no refresh (cache indefinitely)

·         0 means no caching at all (always hot reload)

Starting with JSF 2.3, when the project stage is Production (default) the Facelets refresh period is -1 (no refresh).
