Possible cause for not being able to log into Continuous Testing Platform using Internet Explorer
If you are unable to log into Continuous Testing Platform with Continuous Testing Platform, make sure the domain name does not include an underscore '_'. Using an underscore in the domain name is a violation of RFC 1035. That said, IE silently drops all cookies for that host on a domain that uses an underscore.
Although this is a violation, all other browser (firefox and chrome) work normally.
To workaround this and still be able to use IE to log into Continuous Testing Platform, you can do one of the following things:
1.) Use the IP of the host to navigate to Continuous Testing Platform instead of the host name.
2.) Add a new alias for that domain that uses a hyphen " - " instead of an underscore " _ ".
