Yeah the cause is, nobody has yet written the https://developer.mozilla.org/docs/Web/HTTP/Headers/X-Requested-With article.

So the task for whoever works on this would be to write that article.

[techsin]

how do I find out who works on that?

@techsin This is open source, so it could be anyone - you're most welcome to take it on. At some point if my list of things got small enough I might take it on.

Using a link checker found the following headers with broken links. Do we need all of these to have their own:-

• Viewport-Width
• Width
• Max-Forwards
• Origin-Isolation
• X-Download-Options
• X-Permitted-Cross-Domain-Policies
• X-Powered-By
• Last-Event-ID
• Ping-From
• Ping-To
• Report-To
• Sec-WebSocket-Key
• Sec-WebSocket-Extensions
• Sec-WebSocket-Protocol
• Sec-WebSocket-Version
• Accept-Push-Policy
• Accept-Signature
• Push-Policy
• Signature
• Signed-Headers
• Service-Worker-Allowed
• X-Firefox-Spdy
• X-Pingback
• X-Requested-With
• X-Robots-Tag
• X-UA-Compatible

say if someone wanted to fill out the docs, would they be using w3specs as a reference?

Yes. Though there are plenty of headers that are not in W3C specs - e.g. the Sec-* ones I talk about here: https://github.com/mdn/content/pull/4907#issuecomment-845694070

Further there may be some not even mentioned on MDN yet.

But yes, over time we should aim to document all headers that have been broadly implemented. I will get to Viewport-Width and Width sometime soon as part of https://github.com/mdn/content/pull/4907

FYI very soon most of these broken links will start showing up as red links. No link checker required.
