以编程方式清除 IE 缓存与 InetCpl.cpl,ClearMyTracksByProcess

我有一个托管网络浏览器控件的应用程序，它使用我的微软提供的代码示例（定期）清除缓存：http://support.microsoft.com/kb/262110

然而，我注意到，一段时间后，缓存会损坏或无法正常工作（应该超出缓存的请求 - 会被一遍又一遍地调用。

当我运行以下命令时，应用程序开始正常运行。 系统（'RunDll32.exe InetCpl.cpl，ClearMyTracksByProcess 8'）

两者是否相同，或者代码是否缺少某些内容？

在 IE9 中，我运行了 InetCpl.cpl,ClearMyTracksByProcess 8，它没有删除任何东西，所以看起来 MS 再次移动了球门柱。

下面显示的是我挑选的一些非常好的代码，应该可以在 IE7 中运行，但如果您想要在 win7 和 IE8/9 上运行的代码，请单击我的名字

public static class ClearMyTracks {
 /*
  * To clear IE temporary Internet files – ClearMyTracksByProcess 8
  * To clear IE browsing cookies – ClearMyTracksByProcess 2
  * To clear IE browsing history – ClearMyTracksByProcess 193 (ALSO deletes add on history)
  * To clear IE form data- ClearMyTracksByProcess 16
  * To clear IE remembered passwords for filling web login forms-ClearMyTracksByProcess 32
  * To clear or delete all IE browsing history – all of above!- ClearMyTracksByProcess 255
  * To clear IE Tracking- ClearMyTracksByProcess 2048
  * Preserve Favourites use 8192
  * To clear IE Downloaded Files- ClearMyTracksByProcess 16384
