Integer: 1–INT_MAX.

How to set

Shown in precedence order (see Configuration precedence):

session.xml—Sets the session default.

API—Set as TTS_PARAM_CACHE_TIMEOUT_OPEN in TtsSetParamsEx.

Set in a Vocalizer configuration file (tts_config.xml).

Usage

Useful when troubleshooting performance problems and determining that downloads stall because the web server frequently validates cached data; there is high contention for the entry across instances.

If this timer expires, Vocalizer logs a warning and re-fetches the URI.
