Question

What would be the best way to cache an actionresult forever, that is untill the application is restarted.

// Cache this result forever, it will reset on app restart
[OutputCache(Duration=999999)]
[ChildActionOnly]
public ActionResult Footer()
{
    if (HttpContext.Application != null && HttpContext.Application.AllKeys.Contains("Version"))
        return Content(HttpContext.Application["Version"].ToString());

    return null;
}

Is there a better way to do this?

Answer 1

I don’t know a better way. You can create your own attribute ForeverOutputCache, which will set Duration = Int32.MaxValue in constructor, but this is almost same approach.
