From AOLserver Wiki
- ns_connsendfp - Write bytes from an open channel to the current connection's socket.
- ns_connsendfp ?connId? chanId nbytes
- This command writes the contents of a file or other open channel referenced by chanId immediately to the current connection's socket. It can be used in place of ns_returnfp or ns_respond to send back responses. AOLserver will not include any headers when using ns_connsendfp.
- You must specify the number of bytes to be copied in the nbytes argument. chanId is channel identifier such as returned by the Tcl command open.
- This command is deprecated in favor of ns_writefp, which does the exact same thing. The difference is ns_writefp allows the nbytes argument to be omitted but it does not accept the legacy connid parameter.
