Description

Removes one or more objects from the cache.

Returns

Nothing.

Function syntax

CacheRemove(id, [boolean throwOnError, String region, boolean exact])

CacheRemove(id, [boolean throwOnError, String region, boolean exact])

History

ColdFusion (2018 release): Renamed the parameter key to region.

ColdFusion 11: The ids parameter will also accept an array.

ColdFusion 10: Added the parameters region and {{exact}}.

ColdFusion 9: Added the function.

Parameters

Parameter	Description
id	A comma delimited string of IDs of the cached objects to remove. Starting from ColdFusion 11, you can also specify an array of IDs.
throwOnError	(Optional) A Boolean value specifying whether to throw an exception if any ID does not specify a cached element. The default value is false.
region	(Optional) Name of the cache region from which to remove the cached objects.
exact	(Optional) If true, the search narrows down to values that exactly match the IDs (for removal). The default value is true.

Example with parameter exact set to true

// get all cache ids of cache region, myRegion

Writedump(cacheGetAllIds("myRegion",true));

//array of all cache ids are below:

// CACHE_1

// CACHE_3

// CACHE_2

// when exact=true, does not remove any objects, as no ids match

CacheRemove("cache",true,"myRegion",true);

Writeoutput("All cache ids are");

try{

Writedump(cacheGetAllIds("myRegion"));

}

catch(any e){

WriteOutput("Error: " & e.message);

}

</cfscript>

<cfscript> // get all cache ids of cache region, myRegion Writedump(cacheGetAllIds("myRegion",true)); //array of all cache ids are below: // CACHE_1 // CACHE_3 // CACHE_2 // when exact=true, does not remove any objects, as no ids match CacheRemove("cache",true,"myRegion",true); Writeoutput("All cache ids are"); try{ Writedump(cacheGetAllIds("myRegion")); } catch(any e){ WriteOutput("Error: " & e.message); } </cfscript>
