A client-supplied value isn't going to be too useful - it can be spoofed, or may not be present. (I believe a Windows browser would set the mime-type based purely on the file extension, though I haven't tested this myself). >Marek Kilimajer wrote: > >> If you have compiled php with --enable-mime-magic, you can use >> mime_content_type() This is the most-benefit least-effort choice if it's available, though I believe that flag has been changed since 4.32[?]
