We have an internet facing on premises web app for our external users. We are considering embedding a Mendix app within an IFRAME in this web app. We have embedded other applications by passing a token with embedded data based on a shared secret e.g. the src for the IFRAME element would be something like https://www.someapp.com/somepage?token=asjdasjkfjkhsdfkhjl The someapp.com web app knows how to decrypt the token and get the embedded data. That allows us to be sure what user accessed https://www.someapp.com/somepage so when we retrieve the data they enter we know who it was. Is there a similar way to do this in Mendix or an alternative method of authenticating the users accessing Mendix via the IFRAME. A logon screen in the IFRAME is not a desirable outcome.
