Zones in Internet Explorer 6
SUMMARY
This article describes the changes to the security settings for the Web
content zones in Internet Explorer 6.
MORE INFORMATION
Unless an exception is listed in the following sections, your current
security settings are retained when you upgrade to Internet Explorer 6.
However, the security level for all zones is set to Custom.
For additional information about your security level being set to Custom,

If you click Default Level for any zone on the Security tab of the Internet
Options dialog box, you can apply the new default settings.
Changes to All Zones Settings
When you click Custom Level on the Security tab of the Internet Options
dialog box in Internet Explorer 6, the following settings have been removed
from the Security Settings section:
The Cookies settings have been moved from the Security tab to the Privacy
tab. These settings are not retained when you upgrade to Internet Explorer

The settings that are located under the Microsoft VM heading, which
contains the "Java permissions" subheading, are not present if the
Microsoft virtual machine (Microsoft VM) is not installed. If the Microsoft
VM is installed as a stand-alone package or by means of "install on
demand", these settings are added back.
The following new settings have been added to the Security Settings section
when you click Custom Level on the Security tab of the Internet Options
dialog box in Internet Explorer 6:
Under the Miscellaneous heading, the "Don't prompt for client certificate
selection when no certificate or only one certificate exists" setting is
set to Disable for all security levels, except for the Low security level
(by default, only the "Trusted sites" zone has a Low security level).
The preceding setting had been added to Internet Explorer 5.5 Service Pack
1 (SP1). When this setting is set to Disable, Internet Explorer does not
prompt you with a "Client Authentication" message when you connect to a Web
site that has no certificate or only one certificate. The versions of
Internet Explorer prior to version 5.5 SP1 display the following "Client
Authentication" message even if the Web site does not have a certificate or
has only one certificate:
Identification
The Web site you want to view requests identification. Select the
certificate to use when connecting.
Under the Miscellaneous heading, the "Allow Meta Refresh" setting is set to
Enable for all security levels (except for the High security level) and the
Meta Refresh setting continues to work as it did in previous versions of
Internet Explorer. At the High security level (by default, only the
"Restricted sites" zone has a High security level), the "Allow Meta
Refresh" setting is set to Disable and the Meta Refresh setting does not
work.
The Meta Refresh setting (tag) enables the author of a Web page to redirect
your browser to another Web page after a specified amount of time. For
additional information about the Meta Refresh setting, refer to the
following Microsoft Web site:
http://msdn.microsoft.com/workshop/browser/mshtml/reference/ifaces/metaeleme
nt/content.asp
NOTE: This setting does not function in the Internet Explorer 6 Public
Preview (Version 6.00.2462.0000). This problem was first corrected in the
Internet Explorer 6 Public Preview Refresh (Version 6.00.2479.0006).
Under the Miscellaneous heading, the "Display mixed content" setting is set
to Prompt (which is the same behavior as previous versions of Internet
Explorer) for all security levels, and you may receive the following
"Security Information" message on the Web pages that contain both secure
(
https://) and nonsecure (
http://) content:
This page contains both secure and nonsecure items.
Do you want to display the nonsecure items?
If the "Display mixed content" setting is set to Enable, you cannot receive
the preceding message and nonsecure content can be displayed. If the
"Display mixed content" setting is set to Disable, you cannot receive the
preceding message and nonsecure content cannot be displayed.
Changes to Restricted sites Zone Settings
The following "Restricted sites" zone settings have been changed:
The Active Scripting setting is set to Disable, and your previous setting
is not retained.
The Java Permissions setting, which is located under the Microsoft VM
heading, is set to Disable Java, and your previous setting is not retained.
The "Script ActiveX Controls marked as safe for scripting" setting is set
to Disabled, but your previous setting is retained.
The "Allow Meta Refresh" setting is set to Disabled.
NOTE: By default, the "Restricted sites" zone is used by Microsoft Outlook
Express 6, and can be used by Microsoft Outlook to restrict active content
in Hypertext Markup Language (HTML) e-mail messages.
