Simple cache manager for ColdFusion. Relies on the user to store the component instance in a persistent scope (eg Application, Server, or Session)

cache.cfc

component output="false" {
	public function init(){
		variables.cache={};
		return this;
	}
	public void function put(key, data, timeout){
		variables.cache[key] = { timeout=arguments.timeout, data=arguments.data };
	}
	public boolean function has(key){
		return (structKeyExists(variables.cache, arguments.key) && dateCompare(now(),variables.cache[arguments.key].timeout) == -1);
	}
	public function get(key){
		if (has(arguments.key)){
			return variables.cache[arguments.key];
		}else{
			throw(message="Key does not exist or cache has timed out.", errorCode=-1);
		}
	}
