Article ID: 961712 - View products that this article applies to.
If you press F5 to refresh the page, the page is rendered correctly. However, if you change the selected item in the list in the update panel, the error occurs again.
Internet Explorer cannot open the Internet site
<URL of the Web page>
This problem occurs if a user has a slow network connection. If the user selects an item from the drop-down list in the update panel before the page has rendered the closing <body> tag, an error occurs that causes a redirect to the error page. This error page appends the anchor tag to the document body. When the <body> tag has not been closed, Internet Explorer cannot open the Internet site.
