To cancel a replication simply DELETE the
document which triggered the replication. The Couch log will
show you an entry like the following:
[Thu, 17 Feb 2011 20:16:29 GMT] [info] [<0.125.0>] Stopped replication `c0ebe9256695ff083347cbf95f93e280+continuous+create_target` because replication document `doc_A` was deleted
You need to DELETE the document that
triggered the replication. DELETEing
another document that describes the same replication but did
not trigger it, will not cancel the replication.
