I work on a client-server application that needs to be supported on both
UNIX and windows platforms.
Currently, we keep one socket open for all communication from client to
server (during which many read-write operations take place)
For user authentication and security purposes, we are planning to
I have developed a small ssl client (based on sclient.c example) which
connects to the Stunnel Server.
Upon the first SSL_write, SSL is closing the underlying socket. Hence
the contents written by subsequent SSL_write operations are not visible
in the server log.
I saw lot of posts on the same problem. But couldn't find the solution.
Any help is greatly appreciated.
Please note that:
1. Due platform independency issues, I use RWSocket (a Roguewave library
class) instead of the BSD socket in conjunction with SSL.
