Dear Monks

I'm working on a Perl LWP script, which reads the binary data and the HTTP headers and forwards the data packet to another URL.
This is a POST request. I'm able to send the data using "cURL" request without errors but getting "403 - Forbidden" error when trying to forward the data through the script to the same url.

Below is the "cURL" request which is working fine 
curl -H "User-Agent: myBrowser"  -H "X-version: 2" -H "X-subject: MyTe
+st001" -d@/tmp/SAMPLE.gz -X POST http://mycompany.xxx.com/2.0/post -v

Below is my script (postreq.pl)

which has trouble submitting the data to the url "http://mycompany.xxx.com/2.0/post"
I use the following curl command to test my script
curl -H "User-Agent: myBrowser"  -H "X-version: 2" -H "X-subject: MyTe
+st001" -d@/tmp/SAMPLE.gz -X POST http://testmachine.xxx.com/cgi-bin/p
+ostreq.pl -v
