Re: luasocket/soap: can I keep the connection open?

Hi,

The problem with persistent connections is that your code has to be
robust to the server sending 100 status or not, and closing the
connection on you or not. I am sure different servers will disrespect
the standard in different ways, which means more debugging. You also
need to create an API that hides this complexity from the user in some
way.

It would have taken me a lot more than 15 minutes to do it, so it
would be great if Mr. Quack could find that piece of code... :)

If getfd() is returning -1 then somewhere some C code wrote -1 to the socket.
Look for SOCKET_INVALID. I would have happened either in usocket.c or
in wsocket.c. Somebody is calling socket_destroy() on this socket.

PS: On the other hand, if the server is closing the connection, then
you have other problems to solve as well.
