Returns the description of a specific Amazon File Cache resource, if a FileCacheIds value is provided for that cache. Otherwise, it returns descriptions of all caches owned by your Amazon Web Services account in the Amazon Web Services Region of the endpoint that you're calling.

When retrieving all cache descriptions, you can optionally specify the MaxResults parameter to limit the number of descriptions in a response. If more cache descriptions remain, the operation returns a NextToken value in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

This operation is used in an iterative process to retrieve a list of your cache descriptions. DescribeFileCaches is called first without a NextTokenvalue. Then the operation continues to be called with the NextToken parameter set to the value of the last NextToken value until a response has no NextToken.

When using this operation, keep the following in mind:

• The implementation might return fewer than MaxResults cache descriptions while still including a NextToken value.
• The order of caches returned in the response of one DescribeFileCaches call and the order of caches returned across the responses of a multicall iteration is unspecified.
