Symptom:
We've encountered an issue with our Salesforce.com integration of the Cisco Finesse API. There we use the tunnel IFrame hosted in the Cisco Finesse server to establish a connection to the Open Fire Service of Cisco Finesse to receive Events. Because we are outside the standart Cisco Finesse Desktop and therefore a non-Gadget.

We recognized, that in case the user is following any link, the connection to Cisco Finesse Openfire Service is being terminated in the tunnel frame provided by Cisco.

The link causing the connection to abort:
<a href="javascript: void(0);" id="clear">clear</a>

This links triggers the onbeforeunload event in IE9 and IE10 and the Cisco tunnel catches this event and sends a XMPP terminate request to the Finesse Server.

Conditions:
IE9 and IE10
