The localization complete guide presents an example of how to achieve this using the VaryByCustom parameter. In global.asax you would override the GetVaryByCustomString method:
public override string GetVaryByCustomString(HttpContext context, string value)
{
if (value == "lang")
{
return Thread.CurrentThread.CurrentUICulture.Name;
}
return base.GetVaryByCustomString(context, value);
}
and then:
[OutputCache(Duration = 60 * 10, VaryByParam = "none", VaryByCustom = "lang")]
public ActionResult Index()
{
/* do magic here */
...
}
Or if you want to rely solely on the culture route data parameter you could do this:
public override string GetVaryByCustomString(HttpContext context, string value)
{
if (value == "lang")
{
var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(context));
var culture = (string)routeData.Values["culture"];
if (!string.IsNullOrEmpty(culture))
{
return culture;
}
}
return base.GetVaryByCustomString(context, value);
}
