The UA string as defined in `w3m-user-agent' is, in my system at least "Emacs-w3m/1.4.632 w3m/0.5.3+git20190105", it seems to be made up of the version numbers of Emacs-w3m and w3m(1), which are BTW derived/also present (?) from/in `emacs-w3m-version' and `w3m-version'. However what they speak of in that URL is a string that states in what form the server should grant a HTTP request from the browser. I didn't find any Emacs-w3m variable for that but outside of Emacs-w3m but still in Emacs this sounds like it: url-mime-accept-string String to send to the server in the Accept: field in HTTP requests. I don't know what that package is tho, nor if it is used by Emacs-w3m. Its nil anyway. -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
