In the Key list, choose Cache-Control or Expires, as applicable.
Cache-Control is newer and usually the recommended method, however, some web performance tools like GTmetrix still check for Expires headers.
MediaPackage sets default Cache-Control headers that ensure correct playback behavior.
Cache-Control: must-revalidate This Cache-Control header tells you, or any proxy server between CouchDB and you, not to cache this response.
CloudFront normally respects a Cache-Control: no-cache header in the response from the origin.
Various Cache-Control headers are respected for fine tuning the cache.
If you are using theexpires helper to set the corresponding header, Cache-Control will be set automatically for you.
You can use the Cache-Control and Expires headers to control how long objects stay in the cache.
This value applies only when your custom origin does not add HTTP headers, such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects.
If you specify values both for Cache-Control max-age and for Expires, CloudFront uses only the value of Cache-Control max-age.
Simpler testing of GET and POST,the possibility to directly investigate headers(for cache-control, Cookies, etc), manipulating Content Types, etc.
For more information about the Cache-Control and Expires header fields, see the following sections in RFC 2616, Hypertext Transfer Protocol-- HTTP/1.1.
The value that you specify for Maximum TTL applies only when your origin adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, or Expires to objects.
You cannot use the HTTP Cache-Control or Pragma header fields in a GET request from a viewer to force CloudFront to go back to the origin server for the object.
To change the cache duration for an individual object, you can configure your origin to add a Cache-Control max-age or Cache-Control s-maxage directive, or an Expires header field to the object.
Be aware that Cache-Control max-age and Cache-Control s-maxage values cannot be greater than the Maximum TTL value set for the cache behavior for which the error page is being fetched.
Configure caching on your webservers, set HTTP cache-control headers, and your website will enjoy being slashdotted any time.
For an example of how to add Cache-Control and Expires header fields using the AWS SDK for PHP, see Upload an Object Using the AWS SDK for PHP in the Amazon Simple Storage Service Developer Guide.
To specify a minimum and maximum time that your objects stay in the CloudFront cache regardless of Cache-Control headers, and a default time that your objects stay in the CloudFront cache when the Cache-Control header is missing from an object, choose Customize.
If the origin adds a Cache-Control max-age or Cache-Control s-maxage directive, or an Expires header: CloudFront caches error responses for the greater of the value in the header or the value of Error Caching Minimum TTL.
For an exception to how CloudFront handles the Cache-Control: no-cache header, see Simultaneous Requests for the Same Object Traffic Spikes.
For web distributions, you can use Cache-Control or Expires headers, and CloudFront minimum, maximum, and default TTL values to control the amount of time in seconds that CloudFront keeps an object in the cache before forwarding another request to the origin.
For more information about how Minimum TTL, Default TTL, and Maximum TTL interact with Cache-Control max-age and Cache-Control s-maxage directives and the Expires header field, see Specifying the Amount of Time that CloudFront Caches Objects for Web Distributions.
When CloudFront receives a response that contains a Cache-Control: no-cache header, it sends the object in the response to the viewer that made the original request and to all of the viewers that requested the object during the pause.
