---------------------------------------

             Summary: Improve cache already exists HTTP code
                 Key: ISPN-11059
                 URL: https://issues.redhat.com/browse/ISPN-11059
             Project: Infinispan
          Issue Type: Enhancement
    Affects Versions: 10.1.0.CR1
            Reporter: Galder Zamarreño
            Assignee: Tristan Tarrant


Creating a cache that already exists currently returns {{400 Bad Request}}:

{code}
curl -v -d '<infinispan><cache-container><distributed-cache name="example" mode="SYNC"><backups><backup site="SiteB" strategy="ASYNC" timeout="30000"/></backups></distributed-cache></cache-container></infinispan>' -H "Content-Type: application/xml" -u developer:$(kubectl get secret example-infinispan-generated-secret -o jsonpath="{.data.identities\.yaml}" | base64 -D | yq -r .credentials[0].password) -X POST $(minikube service example-infinispan-external --url --namespace local-operators)/rest/v2/caches/example
Note: Unnecessary use of -X or --request, POST is already inferred.

ISPN000507: Cache example already exists* Closing connection 0
{code}

More fine-grained behaviour would be desirable: if the cache being created is exactly the same configuration wise, it should return 200. Otherwise, if different it should be 409.
