Ok... just ran into a problem with this beta.
I am configuring the dynamic connection for two sites I have on the same server.
They do have different domain names and when I configure the two different connections -- one to be used with first domain and then one to be used with the second domain, it instead just uses the connection from the first domain even though I have not set up the second domain to even utilize the first additional connection.
---- EDIT ----
Actually, what was happening is that it was caching the old variable so the new connections file didn't take hold.
So my next question or suggestion for this extension would be to put in some cache busting code for the connection file. This should be somewhat easy as it is just a static block of code that I feel would be very beneficial.
