I also checked using curl command window

curl -I http://33.33.33/sample.pl <http://33.33.0.33/sample.pl>

HTTP/1.1 200 OK
Date: Thu, 14 Nov 2013 04:40:46 GMT
Server: Apache/2.4.4 (Win32) OpenSSL/0.9.8y PHP/5.4.19
Content-Type: text/plain; charset=utf-8

using curl command prompt i am getting and able to print the complete
response as expected.
