Issue/Introduction

Exception pages are web pages displayed to users under specific conditions.

An exception page does not fully display in browser when accessing HTTPS website that is denied and set up to return an exception page.

Issue does not occur when accessing an HTTP website which is denied and set up to return an exception page.

The issue is observed when using IE10 setup with "Only secure content is displayed".

Selecting "Show all content" in the browser will display the exception page in HTTPS or HTTP.

Cause

The exception page uses a CSS file that is hosted on a different server. The URL to the CSS file uses an HTTP URL.

For Example:
<html>
<head>
<link rel="stylesheet" media="all" href="http://www.abc.com/css/reset-fonts.css" type="text/css" />
</head>

<body>
  <div id="TEST">
    <p> </p>
  </div>
</body>
</html>


As such, the issue is expected because the webpage is trying to display elements with both secure (HTTPS/SSL) and non-secure (HTTP) web server connections.

This issue is due to browser settings and NOT a proxy issue.
