Adds an automated test for the isolated response scenario when using multiple iframes on the page.
How does this work?
Each iframe becomes the outgoing request's
referrer
. If the iframe provides a check in the request handlers to ignore a matching request if it has areferrer
different from the current iframe'slocation.href
, it will allow two iframes to receive different responses to the same request.
