in a merge replication scenario with pull subscriptions using web synchronization, like we have download only articles, is there a way to achieve upload articles?. We have some articles which are always subscriber to publisher. I read online somewhere (can't locate it again) that web synchronization doesn't support upload only. I also read somewhere that if we put a filter like 'where 1=0), that will stop down flow. But can anyone please comment on if such a filter really improves performance? As opposed to leaving it bidirectional.
