How to embed an iframe with 'x-frame-options: DENY' set

This is part of a series of where we want to experiment a bit with what we can do with our proxy technology apart from our current main use case (co-browsing). With our technology we can basically change HTML pages on the fly and inject for example Javascript. You can read more about this here: https://docs.surfly.com/introduction/the-technology.html#sur...

In the first one we used our proxy approach to enable an open web proxy, which you can find here: https://www.surfly.com/labs-advanced-http-web-proxy/

I'd love to learn about more possible use-cases for this approach.
