Different output cache timeout for different usercontrols

I have s开发者_如何学Goeveral usercontrols which I would like to have a different output cache timeout.

I have tried the following but without success:

• Set cacheprofile (can apparently only be done on aspx pages).

• Do the following in codebehind:

  Response.Cache.SetExpires(DateTime.Now.AddDays(OutputCaching.QuickTimeout))

  Response.Cache.SetCacheability(HttpCacheability.Public)

  Response.Cache.SetValidUntilExpires(true);

  Response.Cache.VaryByParams.IgnoreParams = true;

Apparently only <%@ OutputCache Duration="6000" VaryByParam="" %> works, but isn't there a way to take the duration from a config- or appsettings file?

Technically it is possible based on the Remarks of this article but is think that

HttpCacheability.Server = @ OutputCache

instead of

HttpCacheability.Public

Here is the doc for HttpCacheability, this will help you pick the right choice for you.

Also I think it would be best if you put your code in the Page_Init or Page_PreInit like this:

Private Sub Page_Init(sender As Object, e As System.EventArgs) Handles Me.Init
    Me.Response.Cache.SetCacheability(HttpCacheability.Server)
    Me.Response.Cache.SetExpires(Date.Now.AddMinutes(10))
    Me.Response.Cache.SetValidUntilExpires(True)
    Me.Response.Cache.VaryByParams.IgnoreParams = True
End Sub
