When used with the expire action, any resources in the VoiceXML
cache will be marked as expired and deleted from the system (disk).
Unless suppressed by also specifying the -force option,
a warning is displayed when this option is set. The -delete
vxml option is designed for disposing of VoiceXML cache items
from dynamically generated URIs that include a date-timestamp or other
unique identifier, which makes re-fetching such cached items difficult.
It should not be used with resources that are likely to be re-fetched
by an application in the near future. It cannot be used with Audio
cache or CCXML cache resources.By default, Blueworx Voice Response retains
expired cache items so that they can be re-fetched easily if modified.
With dynamic documents, the HTTP header Cache-Control value
can be set to no-cache to avoid caching resources
that cannot be re-fetched.
