    `Content-Encoding` header

    + +

    The `Content-Encoding` header is largely defined in HTTP. Its processing model is +defined here as the model defined in HTTP is not compatible with web content. [[HTTP]] + +

    +

    To +extract an encoding type from a header list headers, run these steps: + +

      +

    1. Let values be the result of + getting, decoding, and splitting `Content-Encoding` from + headers. + +

    2. If values is null, then return null. + +

    3. Let candidateValue be null. + +

    4. +

      For each value of values: + +

        +

      1. If candidateValue is null, then set candidateValue to + value. + +

      2. Otherwise, if value is not candidateValue, return failure. +

      + +

    5. If candidateValue is the empty string or has a code point that is + not an ASCII digit, then return null. + +

    6. Return candidateValue, interpreted as a string. +
