こんにちは、データセットをGlobal.asaxファイルに保存するために以下のコードを開発しました。それをファイルで消費するためにwebpage.aspx.vb、今では正常に動作しています。

同様に、どのようにストアド プロシージャを呼び出すことができますGlobal.asaxか?
助けてください、よろしくお願いします！ 

Shared _cache As Cache = Nothing

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
    _cache = Context.Cache
    RefreshCache(Nothing, Nothing, 0)
End Sub

Private Shared Sub RefreshCache(ByVal key As String, ByVal item As Object, ByVal reason As CacheItemRemovedReason)
    Dim adapter As New SqlDataAdapter("SELECT * FROM dbo.table where logid = 1", "server=server;database=database;uid=userid;pwd=password")

    Dim ds As New DataSet()
    adapter.Fill(ds, "Quotations")

    Dim onRemove As CacheItemRemovedCallback

    onRemove = New CacheItemRemovedCallback(AddressOf RefreshCache)

    _cache.Insert("Quotes", ds, New CacheDependency("C:\AspNetSql\Quotes.Quotations"), Cache.NoAbsoluteExpiration, Cache.NoSlidingExpiration, CacheItemPriority.[Default], onRemove)
End Sub
