Hi
we are getting Http respone code is 0(Zero) and CURLcode is
CURLE_COULDNT_CONNECT
for that request with our http client application.

can we do any configuration on network/firewall settings to execute our http
client application in proper way.

Target machine is Microsoft Windows Server 2003, Standard Edition

Thanks,
Satya.
