Internet Explorer Caching asp.netmvc ajax results

Question

I'm having an issue with a page in internet explorer. I have an ajax call that calls a form, in other browser, when I click the link it passes in the controller and load correctly data. but in IE, when its loaded once, it aways brings me the same old results without passing in the controller.

Answer 1

Try:

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]

This attribute, placed in controller class, disables caching. Since I don't need caching in my application, I placed it in my BaseController class:

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public abstract class BaseController : Controller
{

Here is nice description about OutputCacheAttribute: Improving Performance with Output Caching

You can place it on action too.

Answer 2

You could try setting the cache option to false:

$.ajax({
    url: '/controller/action',
    type: 'GET',
    cache: false,
    success: function(result) {

    }
});

This option will force the browser not to cache the request.

UPDATE:

Based on the comment you could add a unique timestamp to the url to avoid caching issues:

var d = new Date();
var myURL = 'http://myserver/controller/action?d=' + 
    d.getDate() + 
    d.getHours() + 
    d.getMinutes() + 
    d.getMilliseconds();
