IE Enhanced Security Configuration and Smart Clients on SSL

The enhanced security configuration adjusts the Internet Explorer extensibility and security settings. These settings can be found on the Advanced tab of Internet Options in Control Panel. One of adjustments is to turn on the "Do not save encrypted pages to disk" option.

If you have a Windows Forms control embedded to a Web page and the virtual directory containing the control is configured to turn on the "Require secure channel (SSL)" option to support HTTPS, then you should notify users to turn off the "Do not save encrypted pages to disk" option on client IEs, that prevents downloading the control on client machines.

The "Do not save encrypted pages to disk" option corresponds to the registry value "DisableCachingOfSSLPages" under the key "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings".
