When you add new post, the website may not be updated immediately, with a delay of up to 24 hours
If you want to see the updated content immediately, you can clear the cache

Invalidating Files

By Command: aws cloudfront

First, use list-distributions to find out distribution ID

1

aws cloudfront list-distributions | grep Id	# find your distribution ID

grep command can’t be used by CMD (Windows)
Cmder is recommended, remember add it to system path

When you find the ID, use create-invalidation command to clear cache
