Apps for Excel Online and IFrames RRS feed

  • Question

  • We've just submitted an app for approval. The report we received indicates that the app doesn't load in Excel Online. This is because we include an X-Frame-Options: DENY header when we serve the app, which tells the browser not to render it in iframes.

    We really don't want to leave off that header, for security reasons. Not very many browsers support X-Frame-Options: ALLOW-FROM, so I don't think that's a good option. Is there some way to render the app without iframes? Or some other solution that doesn't involve compromising security? We can't be the only ones who have run into this.
