Fun Fact: When http first came out and was hidden in Academia, there were no headers. Then the need for metadata was realized and second-system syndrome took over to create a bunch of crazy headers. My favorite odd-ball header is "Charge-To:" https://www.w3.org/Protocols/HTTP/HTRQ_Headers.html https://www.w3.org/Protocols/HTTP/HTRQ_Headers.html This is not a custom X- header but an official header. Also Email: and some other odd headers were standardized at that time.
