Hi Chitra,
I had similar requirement and here is what I did: -
REPORT  Z_HTTP_POST_TEST_AMEY.

Also, following is the detailed link for use of HTTP_CLIENT class: -
http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/1f/93163f9959a808e10000000a114084/content.htm
Also, in below link, you can ignore XI specific part and observe how its sending XML to external URL:-
(I know it describes call to SAP XI server's URL, but it can be used to call any URL)
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/ae388f45-0901-0010-0f99-a76d785e3ccc
In addition to all above, following configs to be present at ABAP application server: -
1. The hostname used to URL should be present in SAP ABAP application server's 'hosts' file.
2. Security certificate (if available) for URL to be called must be installed in SAP ABAP application server.
Let me know if you achieve any progress with it...
