I am looking for a feature which should be able to check the node destination before save it in the database. This will be used in multi site Drupal set up.
And it must be work like if node 1 has already created in site1 and I want to save node 2 in site2 then it save the node with nid=2 in the site2's node table.
Which means the nid must continues its sequence regardless of domains. Here, database and codebase are same only tables are having different prefixes.
