Creates a cache policy.
After you create a cache policy, you can attach it to one or more cache behaviors. When it's attached to a cache behavior, the cache policy determines the following:
The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.
The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.
The headers, cookies, and query strings that are included in the cache key are also
included in requests that CloudFront sends to the origin. CloudFront sends a request
when it can't find an object in its cache that matches the request's cache key. If
you want to send values to the origin but not include them in the cache key,
use OriginRequestPolicy.
For more information about cache policies, see Controlling the cache key in the Amazon CloudFront Developer Guide.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateCachePolicy and EndCreateCachePolicy.
