The title pretty much says it all, but here's the issue. I have an generic handler that returns Javascript; the only line of code that deals with caching that I put in is the following:

    context.Response.Cache.SetCacheability(HttpCacheability.Public);
    context.Response.Cache.SetExpires(DateTime.Now.AddYears(1));

    context.Response.ContentType = "text/javascript";
    context.Response.Write("result");

I'm debugging on localhost. out of Visual Studio 2008, (that's "localhost." so fiddler picks it up) and Fiddler2 sees the expire date, but says that the cache header is set to private, and the page isn't being cached. Can anybody see what's going wrong here?
