Unable to recieve PUT Data using Code Igniter, REST, Lighttpd url-rewrite and Backbone.js

Question

I am using CodeIgniter with REST APIs and Backbone.js. Web server is lighttpd. I also have lighttpd.conf changed for rewriting URLs to remove index.php from urls as follows:-

url.rewrite-once = (
 "/(.*)\.(.*)" => "$0",
 "/(css|files|img|js|stats)/" => "$0",
 "^/([^.]+)$" => "/index.php/$1"
)

The call from js reaches to Codeigniter Put function but the value for $this->put() is empty. Please help me out in tracing why the value for PUT data is empty.

Note: This works perfectly fine when I don't rewrite the URLs. Also this works for Apache web server.

On debugging REST_Controller.php file, in the function "protected function _parse_put()", I found out that the contents of file "php://input" is also empty

Following is the Request Headers and Payload taken from Chrome Web inspector, while making a PUT Call:-

you can use Backbone.emulateJSON = true;
