NonImgExpiration

Client cache TTL for non-image responses. Provides the expiration interval for certain non-image responses.
Provides the expiration interval for certain non-image responses, including those sent in response to the following commands:
  • req=imageset
  • req=catalogprops
  • req=exists
  • req=imageprops
  • req=props

Properties

Real number, 0 or greater. Number of hours until expiration since the reply data was generated. Set to 0 to always expire the reply image immediately, which effectively disables client caching for default image responses. Set to -1 to mark as never expire .

Default

Inherited from default::NonImgExpiration if not defined or if empty.
TTL (Time-To-Live) is the duration before the cache expires. The default TTL is 6 minutes.
