Method 1

I avoid ViewState client-side entirely by putting it server-side. The code is about 5 lines long and I’ve seen a tremendous improvement in performance.

You could fake a tampered viewstate easily using fiddler:

Method 2

How have you ascertained it is a proxy server? It doesn’t sound likely that a proxy server would truncate parts of the HTML.

However, if ViewState is interfered with then ASP.NET will throw an Invalid Viewstate exception. So, erm,

throw new System.Web.UI.ViewStateException();
