Multiple RAP applications within <iframe> [message #851949]

I have a handful of simple RAP applications (i.e. uses IEntryPoint without a Workbench) that I am trying to integrate with a existing web-application container that uses iframes to render a variety of other web-pages together (i.e. similar to Google Gadgets).

Everything works fine as long as only one RAP application is displayed. If I display two RAP applications, either from the same server or different servers, I start running into issues.

One of two error messages occur:
a) "Multiple browser-instances or browser-tabs per session are not supported..."
b) "The server session timed out..."

My questions are:
1) Is this a known/expected behavior or do I have some misconfiguration?
2) I have some ability to patch the existing web-application; is there a patch that can be made such that RAP works in this configuration?
3) If this is a fundamental limitation of RAP I would be happy to try and resolve it and provide a patch back to the community; it would help if I could be pointed in the right direction to start working on this.

Thanks,
~Michael

Michael,

the error messages might occur because the browser sends the same
session-cookie for all iframes.
You could try to force the browser and server to url-encode the
session-id into the request URL [1].
