Hi, I'm having issues getting OutputCache to work with the remoteDatasource dropdown demo.  Whenever I run through Fiddler, I get this message "HTTP/1.1 Vary Header is present: *
*: The server MUST be contacted to verify the freshness of this resource."

I can put the outputcache on actions not called through the kendo datasource and they are cached as exptected.  Any ideas?

http://demos.telerik.com/aspnet-mvc/dropdownlist/remotedatasource
@(Html.Kendo().DropDownListFor(m => m.PasswordExpireOptionSelectedID)
    .DataTextField("Text")
    .DataValueField("Value")
    .DataSource(source =>
    {
        source.Read(read =>
        {
            read.Action(ListController.ActionGetPasswordExpireOptions, ListController.ControllerName);
        });
    })
)
// Action snippet
private const int CacheDurationDefault = 86400;

public JsonResult GetPasswordExpireOptions()
{
      // some code here....
     return Json(returnValue, JsonRequestBehavior.AllowGet);
}

Doh, i didn't paste my action snippet with the outputcache attribute.  Corrected version:

[OutputCache(Duration = CacheDurationDefault)]
public JsonResult GetPasswordExpireOptions()
{
    // some code here...
    return Json(returnValue, JsonRequestBehavior.AllowGet);
}

Hello,

We are not sure what the exact problem is. Could you please answer the following questions?


1. Do you see an Ajax request made to the action url in your browser developer tools?
2. You say you can use actions cached in a similar way outside of Kendo UI. Can you show the code that uses those actions successfully?

Answering those questions or providing a runnable sample code would allow us to assist you further.

Hi, I am actually no longer looking into this as my team is moving towards a different caching strategy.  Please feel free to delete this post entirely to avoid confusing others.  If we revisit this, I will start a new thread with more details. Thanks!

Hi, thanks for replying, but my team has decided to postpone implementing a caching strategy for now.  If we revisit, I will start a new thread with more details.  Feel free to delete this thread entirely to avoid confusing others.
