问题
How can I write an ASP.NET (C#) application that will render a page can be permanently cached on the iPhone when it is bookmarked as a "Homescreen Icon"? I have tried setting this on the code behind "Response.ExpiresAbsolute = DateTime.MaxValue;" but to no avail. The server code is still executed every time the home screen icon is launched.

You need to set this up through HTML5 cache and app manifest files. Thw WhatWG group has posted a draft specification.
