Automatic .ldb File Deletion After Closing Connection To The Access DB From ASP Page

I created connection to the Microsoft Access DB using DSN from my ASP page.

<%
Set vpconn = Server.CreateObject("ADODB.Connection")
vpconn.ConnectionString =
"File Name=c:inetpubwwwrootDBDNAME.dsn"
vpconn.Open
' Close connection immediately after opening for testing
vpconn.Close
Set vpconn=Nothing
%>

The Microsoft Access, for every database opened for shared use, creates an .ldb file to prevent users from writing data to pages that other users have locked. Whenever the last user closes a shared database, the .ldb file should be deleted.

It is working; the .ldb file is deleted immediately after closing connection
but not if you open/close this connection from your ASP page.

What I found, the .ldb file is deleted with about 70 seconds delays after closing connection from an ASP page.
