We're trying to get AppPortal to cooperate with Service Now (Istanbul) as a Self Service Application which is viewed from a frame. We can get this to work with a new window, however whenever we try to add the following URL:
https://<appsite>/esd/DefaultForUIEmbedding.aspx to the Self-Service menu under ServiceNow we get a message stating that the content can't be viewed in a frame.

I've tried adding appropriate X-FRAME headers to IIS without any luck.Has anyone been able to get this to work?
