I can open a Firefox 
browser and the designated URL address resolves, but stunnel cannot resolve 
it.  Do I have the configuration wrong or is Windows 7 blocking the 
connection?
 
I'm able to send an 
XML message from by application to 127.0.0.1:3600 and stunnel responds with a 
successful but EMPTY RESPONSE.
 
Thanks in advance 
for your help.
