Hosting SAP JAM OpenSocial Gadgets resource in HCP(HTML5 Applications)?

Hi.

I wan to write a OpenSocial gadget for SAP JAM. And I need to host some files (javascript and binary files).

So I want to have HTML5 Application on HCP that produces files and hosts them. Then the SAP JAM OpenSocial gadget uses them.

However, when I tried to register OpenSocial gadget from SAP JAM with url (https://test-i0xxxxxtrial.dispatcher.hanatrial.ondemand.com/myGaget.xml).

It does not work. OpenSocial Gadget fails to register. I did few experiment and realise that I can access the file in the browsers (but single sign on seems to kick in).

So, here is  my question.

How to configure HCP HTML5 Application so it is truly public (and does not require any sign on)?

Thank you.
