Does anyone know what the "q" factor HTTP headers emitted by Firefox 3 mean?
It only appears in the Accept and Accept-Charset headers.
For example:
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,****/****;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
I've tried trawling the web but I haven't quite found the answer.
Is it some sort of weighting, heuristic value or something to do with localization?
Thanks,
Phil'

This page should clarify the "q" parameter, which comes from "quality factor".
