IE/Edge XMLHttpRequest in custom visual

[junesoo]

Hi guys,

I am embedding my own app as a custom visual. My app involves XHR to my own REST server.

I have successfully embedded my app into the custom visual using Chrome and Firefox.

However, IE and Edge seems to have problem performing XHR.

After a bit of research, I found out that in order for IE/Edge to perform XHR in sanboxed environment, it has to allow-same-origin.

Unfortunately, iframe provided by custom visual is only allow-scripts.

I wonder if anyone managed to perform XHR using IE/Edge with some sort of workaround in PowerBI?

@junesoo,

Not everyone can master this, better to share the code snippet. Leave a comment on GitHub as well.
