Hello,

I have recently written some code using WWW::Curl code to access a remote server and perform an HTTPS POST operation. The problem I encounter is when I try and retrieve the responses contents. I have a dev and a production server and have found that they require different code to do this.

My code on my production server is identical to the perldoc:

 
   my $response_body;
   $curl->setopt(CURLOPT_WRITEDATA,\$response_body);
   print STDERR $response_body;
[download]

My code on my development server I found using a google search:

   my $response_body = "";
   open my $response_handle, '>', \$response_body;
   $curl->setopt(CURLOPT_WRITEDATA,\$response_handle);
   print STDERR $response_body;
[download]

If I run the production code on the dev server I get the error:"Can't use an undefined value as filehandle reference at ?????????.pm line 70.". Also if I try to use the dev code on the production server I get no error and an empty string.

Both servers are running perl 5.10.1, and the same version of WWW::Curl, both are CentOS 6.6, the only difference I have found is the dev is running a 3x series kernel and the production a 2x series kernel. Any insight into why the code is behaving differently, and protecting against it would be greatly appreciated.

Thanks
