CloudFront Invalidation - Table of Contents CloudFront Invalidation Overview Amazon CloudFront allows you to to remove one or multiple files from all edge locations prior to the expiration date set on those files. The invalidation feature is helpful in unexpected circumstances, for instance an occasional update to your website's css file, in which you need to remove the file from Amazon CloudFront. Invalidation can also be helpful in the event that offensive or potentially harmful material needs to be removed before the specified expiration time. Note: Invalidation requests for the first 1,000 files each month are provided at no additional charge; above this level, there is a $0.005 charge for invalidating each additional file.
