Syntax
public sealed class CacheRequestComponent : MessagePipelineComponentBase, IValidator, IEquatable<MessagePipelineComponentBase>, IExtensibleDataObject, IDisposable
Remarks

The response message cache key is constructed from multiple properties of the corresponding request message. The key always includes the message body (only BODY element content for SOAP operations). RESTful message is always keyed by request URI and HTTP method. SOAP message is always keyed by Action header value. In addition, key may contain SOAP headers, HTTP headers, and identity claims values (all or a subset).

Declaration
public string VaryByClaims { get; set; }
