{"question":"How is a quality value in a content negotiation header field interpreted?","state":"grounded","http_status":200,"index_version":"0fc1763d6701","answer":"A quality value in the content negotiation fields is the value of the case-insensitive \"q\" parameter, which assigns a relative weight to the preference for the associated kind of content. [rfc9110#12.4.2] A quality value is normalized to a real number from 0 through 1, with 0.001 as the least preferred value and 1 as the most preferred value. [rfc9110#12.4.2] A quality value of 0 means that the associated kind of content is not acceptable. [rfc9110#12.4.2] If no \"q\" parameter is present, the default quality value is 1. [rfc9110#12.4.2] A sender of a quality value must not generate more than three digits after the decimal point.
