We are building an aggregating server where our service acts as a client to some UA servers and stores/exposes that data to multiple other UA clients. I was wondering if there is a way to ask the upstream UA servers to send us data of type LocalizedText in all the locales they suport so that I can have a single session with them to fetch the strings and serve that data to our clients in the priority order they specify in ActivateSession.

After reading the spec, it doesn’t seem like it’s supported by the standard. I’d appreciate any hints about the best way to do this.

Thanks,

There is no way to do that because an upstream UA server may not have a convenient DB of translations that can be queried (i.e. the upstream UA server gets the data from another system that has no API to do this).

You need to create a session for each set of locales requested by client.
