Chart - allowing the image to be downloaded multiple times

When using the Microsoft Chart Control in ASP.NET, if you edit webconfig, then you can allow multiple downloads of the same chart image using the deleteAfterServicing key with a false value

[configuration]
  [appsettings]
      [add key="ChartImageHandler" value="storage=file;timeout=20;dir=e:\inetpub\whatever\temp\;deleteAfterServicing=false" /]
  [/appsettings>
[/configuration]
