That would be good to know. Once we know we could verify behavior with a change to a local hosts file. One scenario that could conceivably cause a problem would be if some old version of OOo behaved badly when it gets a 404 error, such as getting into a retry loop. We know this did not happen for OOo 3.3.0, 3.2.1 or 3.2.0. But it is worth confirming with earlier versions, if the HTTP logs suggest this is happening. -Rob > Best regards, Oliver.
