html file in iframe downloads upon viewing instead of rendering

[akos.illes]

I have an iframe in a Web Content Article and its source is an html file, which is a file entry in my instance, so I would try to get it with the URL “/documents/{groupId}/{folderId}/{title}”, but instead of rendering the html inside the iframe it auto downloads the file when viewing the page.

The iframe looks something like this:

<iframe allowfullscreen="true" frameborder="0" height="600" src="/documents/100/100/schema.json.html" width="800">

Important notes:

• The Web Content Article is generated from code
  • so I would need a solution which can be written in code like html
• The html file is not viewable by guests
• The Web Content renders on a Display Page Template
• The html file is inside a folder in Documents and media
• When reaching the html file with curl the Content-Disposition is attachment
• The html file has a lot of styles for its content
  • so embedding the html into my page at generation is not ideal, unless there is a good solution for it

Please help me find a solution to show this html file on my Display Page.
