I am currently creating a new version of a website that uses a third party service that can only be accessed through an iframe. This service exclusively works on Internet Explorer (not on Edge) in compatibility mode (and with certain security options set), while the new website is developed with more modern browsers in mind (mainly Chrome).
Is there any way to insert an iframe into the page, and make the iframe load its content with IE's engine even though the page containing it has been loaded in Chrome?
I'm not talking about the "user agent" field in the request header (as discussed in this question), I'm talking about rendering the response with a different browser's engine.
