Hi Robert,

 Thank you very much for your time and response.

 I get it, i have been used the same functionality in PHP it returns me a XML file just like the one with POST. 

 If i hit the URL it will show me "Success" and creates the XML file with the output data. But if i hit using the GET method it just gives the output if i simply paste the URL "https://wwwcie.ups.com/webservice/Void".

I also checked with their documentation the webserice works using HTTPS POST

If you have any idea about this and from what i am trying to say, please do respond back.
