Revision 1039

Added by Jing Tao almost 22 years ago

Add a hub control in write and writeData method. If hub==super, metacat can replicate any document in its database to any server in server list. If it is not super, metacat only replicate local documents to any server in server list. If a document' home host is not itself, metacat only force replicate the document to the document's home host.
