HTTP structured field values (RFC-8941) standardizes HTTP header and trailer values by specifying strict rules regarding data types and the processing of HTTP headers to make new HTTP headers more interoperable.

Even though there is some guidance available on how to specify new HTTP fields, having a rather lax set of rules leads to interoperability issues. RFC-8941 defines a strict set of rules on how to parse and serialize specific data types to make sure that parsers are easier to write, maintain and can parse messages faster.

In this video we talk about the different data types that the working group introduced and how the syntax for new upcoming HTTP fields (HTTP headers / HTTP trailers) will look like.
