Hi ranchers,
I see some headers have values like 'q=0.7' included, what does it mean?
Thank you.

If you are studing for Certification this is probably not going to be asked.

If you want to know what exactly it is, assuming you are working with HTTP protocol and asking about HTTP header, you can read the HTTP specification.

" Note: Use of the "q" parameter name to separate media type
parameters from Accept extension parameters is due to historical
practice. Although this prevents any media type parameter named
"q" from being used with a media range, such an event is believed
to be unlikely given the lack of any "q" parameters in the IANA
media type registry and the rare usage of any media type
parameters in Accept. Future media types are discouraged from
registering any parameter named "q"
