While developing an application that automatically download files, I came across the following URL, which is a file with the following content-disposition header:
Content-Disposition: attachment; filename="setup.exe"; filename*=utf-8''hdplayer_setup.exe
Does anybody know what the values of this header mean, in particular the second filename* parameter? Is it normal that it has two filename parameters?
Chrome, Firefox and Safari all parse this as just hdplayer_setup.exe (and not something broken like utf-8''hdplayer_setup.exe) so it seems to be a valid case. Any idea?
