Know the reason why some webpages are not showing correctly in IE8 when using the IWSaaS proxy and how to resolve the issue.
The issue occurs because of the security model of IE that is based around different zones: the Restricted Sites Zone, the Internet Zone, the Local Intranet Zone, and the Trusted Sites Zone.
By default, sites in the Internet and Restricted Sites zones run in Protected Mode, while sites in the Local Intranet and Trusted Sites zones run outside the Protected Mode. For security reasons, sites from inside and outside the Protected Mode cannot share cookies. This causes some images and text of a webpage to not display correctly.
For example, the site yahoo.com has been moved to the Trusted Sites zone. However, when you access www.yahoo.com, you will also load images and CSS files that belong to the yimg.com domain. IWSaaS will not load the files from yimg.com because the domain is automatically categorized in the Internet Zone by IE and thus cannot share the IWSaaS login cookie with yahoo.com.
To resolve the issue, change the IE settings:
- Open the IE browser.
- Go to Tools > Internet Options > Security.
- Select a zone and tick the Enable Protected Mode option.
Do this for the rest of the zones (Local intranet, Trusted sites, and Restricted sites). - Restart IE.
