Defines the behaviour/header used for sending an etag along with a request.
public enum ETagAction
The default etag behaviour will be determined by the type of the request.
The ETag will be added as an "If-Match" header. A request sent with an "If-Match" header will only succeed if both ETags are identical.
The ETag will be added as an "If-None-Match" header. A request sent with an "If-None-Match" header will only succeed if ETags are not identical.
The ETag won't be added to the header of the request.
