When using Internet Explorer 6, the user was informed the program has encountered a problem with a HTTPS delivered webpage via a modal dialog box. The user was then asked to make a security decision. Internet Explorer 7 follows the “secure by default” paradigm, whose behavior is slightly different - no modal dialog box is presented to the user. Instead, upon encountering a certificate problem, Internet Explorer 7 presents an error page explaining the problem with the certificate. The error page conveys to the user there is a problem with the website's security certificate. The user may choose to ignore the warning and proceed in spite of the certificate error (unless the certificate was revoked). If the user clicks through a certificate error page, the address bar fills with red to serve as a persistent notification of the problem.
Internet Explorer 7 blocks navigation to HTTPS sites that present a digital certificate that has any of the following problems:
- Certificate was issued to a hostname other than the current URL’s hostname
- Certificate was issued by an untrusted root
- Certificate is expired
- Certificate is revoked
If you receive an error message stating that 'Internet Explorer was unable to display the webpage
' when using Internet Explorer 7, you may need to update the browser security settings. Navigate to Tools > Internet Options > Advanced > Security
, and update the settings accordingly.
