SYMPTOMS

The Web page that is used for Explorer view and for Folder view of a document library contains an in-line frame (IFRAME) tag that has a URL that is set to about:blank. The IFRAME tag is later redirected to the correct location by a script. However, when the Web page loads, Microsoft Internet Explorer detects the about:blank URL as a different protocol than the https:// protocol that was originally used connect to the Web site. As a result, Internet Explorer prompts you to verify whether you want to change protocols. After you click either Yes or No on the message, the message no longer appears on your screen, the in-line frame (FRAME) tag is redirected to the correct location, and then the Web page opens in Explorer view or in Folder view as expected.

CAUSE

This behavior occurs if you connect to the document library on the Web site by using Secure Sockets Layer (SSL). This behavior occurs because of the way that Internet Explorer processes the "about:blank" (without the quotation marks) URL that the in-line frame (IFRAME) tag on the Web page is configured to use.

RESOLUTION

To work around this behavior, click either Yes or No on the message that is described in the "Symptoms" section. After you do so, the Web page opens as expected in Explorer view.
