For 4.x-like roaming, (I think) I need to check, if the local file is newer/older than the file on the server before down/upload.
I didn't find an API to get the time when the file/resource on the HTTP and FTP server was last modified. I can get to the raw HTTP headers (probably same for FTP), but of course I'd like to avoid parsing them in my code. My code is mostly protocol-agnostic right now and I'd like to keep it that way. Did I overlook some way to get to that info? If not, would it be reasonable to put that into Necko? Who do you think should the API looks like; most importantly, which interface should contain the method(s)?
