What causes both the RQM and the RTC webUI to repeatedly prompt for a login which does not accept any credentials

There seems to be some issue with timeout with IE8 browser when using RQM (also RTC, not sure about RRC) where any new action would bring up a "bogus" login prompt repeatedly which would not accept any credentials, bona fide or bogus or blank, nor would it issue any error messages. 

·         This would seem to require closing all browsers and restart before you can get a real login prompt.

·         This happen infrequently, but the frequencies have been increasing. So far we cannot make it repeatable at will yet.

·         This seemed to happen with some pause in usage but independent of length of idleness, and there are times that the idle was infinitesimal.

·         We have found later that when this happens, the dashboard home would show This Server is offline or unreachable for all tools (ccm, qm, rm) similar to https://jazz.net/forum/questions/114895/personal-dashboards-shows-this-server-is-offline-or-unreachable

·         We also found that at the bottom of the dashboard home, “LifeCycle Project Admin” and “Jazz Team Server Home” are not greyed out like the rest.

·         If you click on “Jazz Team Server Home” your session may restart at the JTS home, it is more hits than misses, and you will avoid the pain of having to close out all browsers.

·         Also if we replace the server fully qualified name, in the URL, with the short name or its IP address, we may restart the app without having to close all browsers. The short name seem to be more effective than the IP address, but it;s still a hit and miss workaround.

·         One of our tester have the issue happened on the RQM most often around 11:00 AM.
