CF Providers
Our CFColdboxProvider is an implementation specifically written for Adobe ColdFusion 11 and beyond. This provider leverages the EHCache engine within ColdFusion 11 and extends the native ColdFusion capabilities by talking to the EHCache sessions natively via Java. In this manner we are able to do things like:
  • Get extended cached object metadata
  • Get overall cache statistics
  • Talk to terracotta classes
  • Do quiet operations on get, clear, and put
  • Check if an element is expired
  • Do reporting and content reporting
  • Much more

Each CacheBox provider can have its own set of configuration properties it needs for operation. Our CF providers also have some. Please note, all properties other than "cacheName" are passed through to the underlying EHCache implementation in ColdFusion. The default values may differ if you have edited the ehcache.xml file on your server.
Property
Type
Required
Default
Description
cacheName
string
false
object
The named cache to talk to via ColdFusion cache operations. By default we talk to the default ColdFusion object cache.
clearOnFlush
boolean
false
true
Sets whether the MemoryStore should be cleared when flush() is called on the cache
diskExpiryThreadIntervalSeconds
integer
false
120 (2 minutes)
The interval in seconds between runs of the disk expiry thread.
diskPersistent
boolean
false
false
Specifies whether to persist caches stored on disk through JVM restarts.
diskSpoolBufferSizeMB
integer
false
30
The size of the disk spool used to buffer writes
external
boolean
false
false
Specifies whether no timeout or idletime applies. A true value indicates that the object or page is cached without any timespan being specified.
maxElementsInMemory
integer
fasle
10000
The maximum number of objects that can be cached in memory. If the number is exceeded and overflowtodisk is false, the new objects entered replace old elements using algorithm specified in the memoryevictionpolicy entry.
maxElementsOnDisk
integer
false
10000000
The maximum number of objects that can be stored on disk if overfllowtodisk is true.
memoryEvictionPolicy
string
false
LRU
The algorithm to used to evict old entries when maximum limit is reached, such as LRU (least recently used) or LFU (least frequently used).
overflowToDisk
boolean
false
false
Specifies whether when the maximum number of elements allowed in memory is reached, objects can be moved to disk, as determined by the memoryevictionpolicy value.
timeToIdleSeconds
integer
false
86400
The idle time in seconds. Used if a cfcache tag does not specify an idleTime attribute.
timeToLiveSeconds
integer
false
86400
The timeout time in seconds. Used if a cfcache tag does not specify a timespan attribute.
Info Please note that you can configure more than 1 CFColdboxProvider cache engine in your applications that can talk to more than one referenced ColdFusion (EHCache) custom cache.
