– Common Function Library Project


Last updated May 13, 2003

Version: 1 | Requires: CF6 | Library: UtilityLib

Deletes a specified file from the Cold Fusion cfclasses cache directory, forcing ColdFusion to re-compile it. Returns true if successful, false if file was not found. Pass it your cf template's full or partial file name. This is especially great for servers with "Trusted Caching" turned on but you still need to make a change to a page, or for those mean servers that seem to keep files in cache even after updating them.

Return Values:
Returns a boolean.


#DeleteCFCache("bingobangobongo.cfm")# (always false)


Name Description Required
cachedFile Filename, or partial filename. Yes

Full UDF Source:

 Force recompiling of a page in the cfclasses cached folder.
 @param cachedFile 	 Filename, or partial filename. (Required)
 @return Returns a boolean.
