This post is part of my Today I learned series in which I share all my web development learnings.
Recently, I had a quick discussion in Contentful's community Slack about file downloads. The person I was talking to asked if there is a way to add the Content-Disposition header to uploaded assets. Unfortunately, that's not possible, but this header was news to me! 😲
After reading the MDN documentation about Content-Disposition I learned that you could trigger the "Save as" dialog in browsers by applying the response header.
Content-Disposition: attachment; filename="cool.html"
Pretty cool!
