When SessionInvalidSessionEndedButton1Url was added, it was, at least in part, as a result of discussions I had with management regarding the ability to launch a survey at the end of our support sessions. It did not originally include support for parameters. Based on a feature request, support for the passing of session ID and title were added.
SessionInvalidSessionEndedLaunchUrl has now been added, and now also does not support passing paramters.
I asked the question when it was added to the output stream in teh focus group forum, and was told that it was supported:
I've been informed by support that I must now request this as a new feature request, too.
The use case for this is the same one that has driven the rest of this development: we'd like to be able to launch survey at the end of a session and collect feedback on our agents. Similar to GTA, we don't want to have to manually review each survey - we want to pass a session ID or other identifier to the survey page and allow us to link that to the user on the back end so that we know whom to credit the survey to.
