---------------------------------------
Summary: Support ETag / If-Match Headers when using CUD operations
Key: CAMEL-13598
URL: https://issues.apache.org/jira/browse/CAMEL-13598
Project: Camel
Issue Type: New Feature
Components: camel-olingo4
Affects Versions: 2.22.4, 2.21.5
Reporter: Paul Richardson
The [Tripin Reference
server|https://services.odata.org/TripPinRESTierService/(S(4gus0w41xmxedlzbywj2srqo))/$metadata]
supports ETags on its Airlines resource. Consequently, if an update or delete
operation is performed then the following must occur:
# Client calls a GET request & fetches the content of the ETag header;
# Client calls a PATCH/DELETE request complete with an *_If-None-Match_*
header that has a value of the previously queried ETag.
At the moment, attempts to use the camel-olingo4 implementation fail with an
http [428|https://httpstatuses.com/428] code.
