class S3

# Represents a single CORS rule for an S3 {Bucket}.

#

# @example

#

# rule = bucket.cors.first

# rule.allowed_methods #=> ['GET', 'HEAD']

# rule.allowed_origins #=> ['*']

#

# @see CORSRuleCollection

class CORSRule

# @param [Hash] options A hash of the rule details.

#

# @option options [String] :id A unique identifier for the rule. The ID

# value can be up to 255 characters long. The IDs help you find

# a rule in the configuration.

#

# @option options [required,Array<String>] :allowed_methods A list of HTTP

# methods that you want to allow the origin to execute.

# Each rule must identify at least one method.

#

# @option options [required,Array<String>] :allowed_origins A list of

# origins you want to allow cross-domain requests from. This can

# contain at most one * wild character.

#

# @option options [Array<String>] :allowed_headers A list of headers

# allowed in a pre-flight OPTIONS request via the

# Access-Control-Request-Headers header. Each header name

# specified in the Access-Control-Request-Headers header must

# have a corresponding entry in the rule.

#

# Amazon S3 will send only the allowed headers in a response

# that were requested. This can contain at most one '*' wild

# character.

#

# @option options [Array<String>] :max_age_seconds The time in

# seconds that your browser is to cache the pre-flight response for

# the specified resource.

#

# @option options [Array<String>] :expose_headers One or more headers in

# the response that you want customers to be able to access

# from their applications (for example, from a JavaScript

# XMLHttpRequest object).
