How to purge CloudFront's cache

Question

I would like to know if it's possible to clear CloudFront's cache,

The file concerned has changed on Amazon S3 but it's not being updated on CloudFront.

Answer 1

I found the answer using Python:

import boto
cf = boto.connect_cloudfront('key','key2')
cf.create_invalidation_request("distribution_id", ["/path1","/path2"])

Answer 2

In case you use Chrome, you can use this plugin.
