deleting temp internet files

[bintaleb]

Hi everybody

I had a page to update user picture and redirect user to login page, the problem is when a user re-login, the old picture is still available until user refresh the page.

notes: I have already use <&#37;@ output> but not working with master page
and also have used Response.Cache.SetCacheability(HttpCacheability.NoCache) and also not working

here is my code:

Protected Sub btnUpdate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnUpdate.Click
        
        'Updating User Pic
        fuUserPic.PostedFile.SaveAs(Server.MapPath("~\Images\UserPic\" & UserID & ".jpg"))

        Response.Cache.SetCacheability(HttpCacheability.NoCache)
       
        FormsAuthentication.SignOut()
        FormsAuthentication.RedirectToLoginPage("msg=Please login again")
    End Sub

please what can I do to delete temp internet files to display picture after updating?
