Handling errors differently when calling from Ajax

I'm really close to grasping what you're describing, and I think I understand how that's going to work, but I'm not quite able to put all the pieces together.

First confusion-- to initiate the server call on the client side, I have to make an Ajax call somehow, (I mostly use $.post() to do this), so I don't know how I'd get around this. (You mentioned don't do an $.ajax call) Can you give an example of how you start the server call?

I think I can make my way through the rest of what you described if I get my head around this part.
