Hi all,

I'm using LWP::UserAgent to post JSON data to a php script. It's working fine on my Debian machine, but from Windows XP/ActiveState Perl, the post data isn't sent. 

   $req=$ua->post($myurl,
        [$postcontent],
        @netscape_like_headers,
        'Content-Type' => 'application/json; charset=utf-8'
        );

$postcontent is a string, something like: 

{"slv":{"__type":"Presenters.JCMII.Views.SendLetterView","SelectedItem
+Ids":[1,2,3]}}

[download]
When I watch what is being sent with Ethereal/Wireshark, it all looks correct, and works fine: I see the application/json content header, the correct content-length, then \r\n\r\n followed by the post data.

On XP, I see a content-length of zero, and no posted data.

Both machines are running Perl 5.10.0. The XP machine has LWP::UserAgent 5.826, Linux machine 5.810

The script is identical on both machines, and I've checked for silly errors (like $postcontent being empty).

Any ideas what could be causing this? Is it anything to do with the posted data not being in the more common key=value format?
