public class DefaultCorsProcessor extends Object implements CorsProcessor
CorsProcessor
,
as defined by the CORS W3C recommendation.
Note that when input CorsConfiguration
is null
, this
implementation does not reject simple or actual requests outright but simply
avoid adding CORS headers to the response. CORS processing is also skipped
if the response already contains CORS headers.
