Can you try something like this in your /Base method?

using System;
using System.Web;

namespace BaseTest
{
    public class TestClass
    {
        public static string GetCurrentTime()
        {
            HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
            return string.Format("Current time: {0:MM/dd/yy H:mm:ss zzz}", DateTime.Now);
        }
    }
}

@jc, I tried various permutations of that (I tried some of the other caching options too), with no luck, IE still cached it. I'm not sure if it's because the call is wrapped in the /Base methods or not, I need to debug it when I have more time!

For now I've stick with passing in a spurious timestamp to the methods so that they work ok, although I'm definately going to investigate this one further as it's a much neater way of doing it. Also, it amuses me to have a parameter called "fixIE".

:P
