Hi,
The below code is working fine without proxy. If I enable proxy code by
Uncoomenting the proxy setopts code
The code is failing to connect to proxy. I am using curl 7.18.0 version.

I am not able to figure out what could be the problem. Someone can help me
in resloving this issue that will be of great help.

Thanks in advance,
REgards,
PCREddy.
