hi Derek
thank you for the information.
Unfortunately, am having difficulty reproducing the error.
It occurred during a demo, and not since !
note: I am using the javascript API + Feature Layer, so not making any custom direct requests to the ArcGIS server.
re: HTTPS - it is a SharePoint project, and there is javascript using https references, and they actually point to a different server!
so it looks like they are the cause of this message.
Question - would you know how to avoid / disable these warnings in IE8 ?0
I know the user can change a setting, but is there some other way ?
thanks for your help.
