Read vs. write connection

I really don't understand how this product is supposed to work. I created a localhost connection + write connection + a read one. They are all under one connection name and of course in one file. So if I put a php connection line at the top of my dynamic page files and for some pages I want write access and others only read access, how are the connections distinguished using this one file? I ask because so far it's not working. Any insight is appreciated.

the connection is distinguished based on the domain you enter that the connection should be used for


When you create the connection, the Primary Connection tab sets the default connection that will be used.

On the Additional Connections tab, you can specify other connections to use based on the domain.

No I'm still not getting it and as usual the getting started guide is fairly shallow in explaining things. If I put a php connections command line at the top of my files that points to a single file, how do I distinguish (or the connections file do this) between those pages that are only supposed to be a read only connection and other pages that are to be writable also? What do I do different in either defining the php entry at the top of the page or the inputs when creating the multiple connections in Dynamic Connections? Is this understandable how I'm describing?

the connections used by dynamic connections can only change if the domain changes.


If the pages are all in he same domain, dynamic connections will not do this for you, you will need to create 2 separate connections to manage this on a page by page basis.
