Good news from Amazon this morning as they have announced what I’ve been asking for – an API for content invalidation. Previously, they allowed content to have a max-age of 1 hour, but it didn’t allow for the control that a manual invalidation would have. According to the press release, the API call will allow for the removal of files from all edge locations. A set of files can be removed as well.
“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.”
This is great news on 2 fronts:
- It’s a great feature that was missing from an already solid product.
- It’s a sign that Amazon is listening to it’s customers and providing updates without deprecating existing APIs.
Here’s a screenshot of the API call from Amazon’s CloudFront developer documentation:
