a question about persistent mode in http
if in keep-alive mode, in the server side, how can i recongize a persistent connection
is shut down, and free the preserved resources of it? from the appearence of http
request and response, there seems on obvious steps to tell the server an persistent
connection will be terminated. and in the client side, i also can't find any
configuration about whether to choose keep-alive mode. then how the browser knows if i
want a persistent mode?
another question is: now, which web servers and browsers support persistent mode? i
wish there are some open source products i can refer to.
so many questions, thanks in advance.

Subject: using ssl in http protocol
>one question:
>http is a connectionless protocol(at least 1.0 is, and i don't know if
there are some implementations of http1.1). if we want to use ssl in http to
acquire secure connection, then, does it means we have to take the full
handshake for each connection(each request and reply)? if not, how they
implemented it then? are there some little source examples here(both client
and server)?

If what you mean by a "connectionless" protocol is that there is no
mechanism for persistent connections, that is incorrect. HTTP/1.0 does
support persistent connections (using the Connection: Keep-Alive header) and
HTTP/1.1 does it by default.
Hence, if you are communicating to the same HTTPS server, upon a keep-alive
request, the server in most cases will oblige that request and keep the
connection open. However, that is the prerogative of the server.
