HI Phil Sturgeon,

Thanks for the reply.

I just copy pasted your function in the above given file, but it is showing some fatal errors, stating call to undefined function ci::option.

Please give some detailed explanation about how to use the function, where to use and how to call it,

Does the parameteres $url and port changes dynamically or what should be passed.

Please help me Iam very new to curl and proxy settings.

Thanks in Advance.
