Hi, my application uses the API successfully most of the time, but intermittently I get an exception:

User is not authenticated. Access denied.

One thing I have read on this forum is that an idle connection will time out after an hour. In my application I cache the connection object so could this be cause of my exception? If so, is there a good way to 'test' the connection, or do I just have to try to read some data and see if it throws?

Thanks,
Stephen Boissiere
