Question

How can I flush the cache in ASP.NET

Asked by: tariqanis

Hi,

I am relatively new in ASP.NET, trying all sort of things.
I had my first web site published (photo gallery) but wanted to improve performance  because the images were slow to load so I tried the cache for the first time and set the duration of the cached pages to 24 hours.
My initial page used to be a "Welcome.aspx" page which is not cached. It contains a LoginStatus control and a LoginView control. This page was always the first to appear on the site. Now, But now the Default.aspx page shows up first althought the user has not been authenticated and despite the fact the code in the page upload directs unauthenticated users to the Welcome.aspx page.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If User.Identity.IsAuthenticated = False Then
            Response.Redirect("Welcome.aspx")
         end sub

For now I need to flush the cache and see if this would restore the situation to what it was but I am not sure how to do that.

Thanks for your help

Tariq

Hi Crazyman,

I am not sure I understand the usefullness of the code you referred me to.
The cached web pages are already in memory and any code outside these pages (as far as I know) is ignored because it is not looked at.
What I understand is that when a cashed URL is requested the cache supplies it, which means the pages stored in the cache will be rendered and the code in a new page would be ignored.
 I guess the only solution was to replace the pages on the web site with new pages that do not contain the cache tag and wait for the duration of the cache to expire.
Am I mistaken in what I just said??
Please respond because I am trying to learn.
