So, did that fix it for you?

HTTP, yes. REST.... I'm not so sure about.

REST requires that a URL always returns the same data. Unfortunately,
if we have update operations on the database, then the returned data
can change. It is possible to put something like revision numbers into
the URL, but that would require keeping a lot of old revision states
available, which wouldn't be fun (mind you, we could give a "410 -
gone" response for anything that's dropped out. If you, or anyone
else, has idea, then please let me know. I'm the last person to ask
about REST, so I'm happy to take any and all advice.

The main thing missing from the HTTP setup is transactions. I don't
want to maintain state between calls, so I'm thinking I may need some
way to upload scripts to be run in a transaction. Any other ideas here
will be appreciated as well.

Regards,
Paul
