CFLib.org – Common Function Library Project

Description:
This is a variation of the sleep() UDF already on cflib.org. However, fake_sleep() is a bit more "web hosting friendly". If your web host has CreateObject( "java" ) turned off (as mine did), the existing sleep() method will not work. This UDF is a "side step" around that issue. (I've noted it above as "requires MX", however I think CF 5 support is possible as well with a minor edit or 2.)

Return Values:
Returns nothing.

Example:

<cfset fakesleep( 3000 ) />

Parameters:
