Point 3 is your problem, s_client handles stdin in a special
way :(
s_client assumes that if either stdin or the ssl socket
hits end of file, that it should shut down operation.
Unfortunately, when redirecting stdin from a file,
what happens is that you read the command to send to
the remote web server, send it, and then quit before
the response can be read in.
If you need to get around this, the easiest is probably
to go into the s_client code and modify it to not
shut down the connection. We've done this in the past
on older releases of SSLeay, and its about a 5 line
code change. There are a number of ways of doing it,
but here's one:
1) When the FDSET is built to do a select on, have
a flag called "stdin_open" that must be true
before adding stdin to the FDSET.
2) At the start of the main select loop, set stdin_open
to true.
3) When end-of-file is detected on stdin, set stdin_open
to false.
Cheers, Thomas
