<pre class="fixed_text">Cache-Control: post-check=3600,pre-check=7200

If the site administrator removes this custom HTTP header, the problem does not occur.

<div class="moreinformation_section">

MORE INFORMATION
A Post-check directive is a cache-control directive that is included with the HTTP Expires header. Web sites use the HTTP Expires header to control how Internet Explorer caches content on the Web site. Post-check defines a time interval (in seconds) that defines after which an object must be checked for &quot;freshness&quot;. This check allows Internet Explorer to display the content from its cache or in the Temporary Internet Files folder, and then update the cached copy of the content in the background. This update is also known as a lazy update.
