# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# The SSL server hostname may be an IP address, a domain name,
# or "localhost".

# Connect to the SSL server:
success = socket.Connect(sslServerHost,sslServerPort,ssl,maxWaitMillisec)
