There's a few places where I use an iFrame and need to set some specific Header values. I did notice the allowSameOrigin setting can only be set in code (there's no checkbox for it in the inspector window). If ya'll could put a headers property that can only be accessed in js like allowSameOrigin and reload() the iFrame component would be a lot more useful
Thanks for reaching out! I sent this request over to our team. Are you able to share specific headers or use cases that would be helpful? It may help our team assess priority of this request & if it ends up that we can't ship this feature currently, I can put in more specific header requests
they were mostly non-standard 'X-' based headers or CSP related. We were able to work with the host of the iframe target to get things working.
