How do I make single page expiration 1 hour CloudFront

Question

I am using CloudFront to distribute content from one of my domains. There is no S3 tie-in here. By default, content expires after 24 hours, which is fine for most of the data on the website, however, there are a few pages that I'd like to have only a 1 hour cache limit on. How do I go about setting this.

From the CloudFront FAQ:

Q. How long will Amazon CloudFront keep my files at the edge locations? By default, if no cache control header is set, each edge location checks for an updated version of your file whenever it receives a request more than 24 hours after the previous time it checked the origin for changes to that file. This is called the “expiration period.” You can set this expiration period as short as 1 hour, or as long as you’d like, by setting the cache control headers on your files in your origin. Amazon CloudFront uses these cache control headers to determine how frequently it needs to check the origin for an updated version of that file. If your files don’t change very often, it is best practice to set a long expiration period and implement a versioning system to manage updates to your files.
