Hi, RFC 959, says that FTP supports two modes to transfer files -- ASCII and Binary. Now, if I have a UTF-8 (or any other encoding) encoded text file, containing, say Japanese characters, would it be correct to choose the transfer mode as ASCII? And if I choose the transfer mode as ASCII, is

Well, I'm not claiming that latency isn't a factor in protocol performance. What I'm claiming is that it's not clear that latency in the initial connection setup handshake (in this case the TLS one) is a major factor in protocol performance. Recall that the way that TLS works is that you do an

The best solution to this problem is to avoid the use of technical vocabulary and use plain English and unambiguous formulas. It is quite easy to see how the term 'strictly monotonic' gets abreviated to 'monotonic' when used by non-mathematicians. I am pretty sure that if we started using the
