Interesting question.

I am not sure POST goes with Conditional update. Need to check the spec.

Meanwhile - can you use PATCH?

You'd need to roll your own little patch media type. Would be interesting if you shared your use case.


PATCH /contract/42
If-Match: "3"
Content-Type: application/contract-update

<contract-update>
  <set-status>platinum</set-status>
</contract-update>

200 Ok
ETag: "4"
Content-Type: application/contract

<contract>
   <name>Bert</name>
  <status>platinum</status>
</contract>
