RE: Briefly explain how server form post-back works (perhaps ask about view state as well).
Post Back:

The process in which a Web page sends data back to the same page on the server.

View State:

ViewState is the mechanism ASP.NET uses to keep track of server control state values that don't otherwise post back as part of the HTTP form.

ViewState Maintains the UI State of a Page
ViewState is base64-encoded.
It is not encrypted but it can be encrypted by setting EnableViewStatMAC true & setting the machineKey validation type to 3DES.
If you want to NOT maintain the ViewState include the directive < @ Page EnableViewState false > at the top of an .aspx page or add the attribute EnableViewState false to any control.
