:: Details

Working on enterprise web applications when integrating with a 3rd party we need to make use of Window.postMessage() to enable a 3rd party partner rendering content in an iframe to tell the parent window (our window) that it should do something via a message.

Due to the way that large applications are hosted often times the *exact* domain being used may not be known.

e.g. the parent window could be on "https://cdn7.megacorp.com/" and the child iframe on "https://pool3.example.com/" where the subdomain is a variable on BOTH ends of the communication.

It isn't clear if "megacorp.com" is a valid partial domain to post a message to where any subdomain server under "megacorp.com" can receive the messages... or is "*.megacorp.com" a valid option?

As a follow up, if setting a partial domain is NOT a valid option, I'd love to know where to submit a bug to for the actual API spec, since this is a very likely scenario in any enterprise situation.
