cache-control.max-stale
Use only cached data that has exceeded its expiration time by up to the specified number of seconds.
Value |
Integer: 0–INT_MAX (seconds), or -1 to disable (use normal caching). If no value is assigned to max-stale, the server may use stale data of any age. DEFAULT: -1 (use no default) |
How to set |
In the application’s session xml, in the <speechsynth> of the <speechserver> section under <sessionparameters>. In a VoiceXML application, using the maxstale attribute of an <audio> element. In the browser, using the Cache-Control:max-stale header in a RECOGNIZE, DEFINE-GRAMMAR, SPEAK, or LOAD-LEXICON method. For the recognizer—In the application’s session.xml, in the <speechrecog> section of <speechserver> under <sessionparameters>. For the synthesizer—In the application’s session.xml in the <speechsynth> section of <speechserver> under <sessionparameters>. For the recorder—.In the application’s session.xml, in the <speechrecord> section of <speechserver> under <sessionparameters>. |
Usage |
Seldom used. |
Sets a session default for the corresponding MRCP header. The value -1 ignores any default max-age/max-stale value (and Speech Server does not set the max-age/max-stale value in its cache requests).
