SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer(); ie.Visible = true; ie.Navigate("www.example.com"); // Wait for IE to finish loading while (ie.ReadyState != SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE) { } // Clear the cache ie.Document.parentWindow.execScript("void(document.execCommand('ClearAuthenticationCache', false, null));");In this example, a new instance of Internet Explorer is created and navigated to a website. The `ClearAuthenticationCache` command is then executed to clear the cache memory. The package library used in this example is `SHDocVw`, which is part of the Microsoft Internet Controls (MSIC) package.
