Which browsers have problems caching XMLHTTPRequest responses?

Question

Do any of the currently popular browsers have particular problems caching* XMLHttpRequest responses that I need to be aware of?

I\'d like to be able to include XMLHt

Although some browsers have different defaults (by default, IE will cache results from AJAX requests, but Firefox, by default, will not), all browsers that I'm aware of will obey the http headers, such as Cache-Control. So just set the caching headers correctly for your application.

Here is an example:

    public ActionResult SomeAction()
    {
        var model = [...];
        Response.AddHeader("Cache-Control", "no-cache");
        return Json(model);
    }

Now IE and Firefox will both behave the same; they will never cache the results of the action.
