Is there an option for 'http' protocol communication with 'file' protocol?

[Greg Howdeshell]

Is there a way easyXDM can communicate between iframed content and a static html page stored on a local drive?  I'm running into CORS concerns with an error message noting: "Uncaught SecurityError: Blocked a frame with origin "http://localhost:3000" from accessing a frame with origin "null".  The frame requesting access has a protocol of "http", the frame being accessed has a protocol of "file". Protocols must match."  I'm reviewing easyXDM as a solution but before I dig into it too much wanted to throw out my roadblock.  Thoughts or alternative solutions?

Hi Greg, this is not possible since file comes with a non-defined security model, which makes it close to impossible to write any deterministic code.

You should be able to use regular postMessage between the two iframes though.

Hmm, really a pain to solve this issue.  In an attempt to perform a generic post message, the post still requires a valid host name.  So that didn't seem to work either.
