301 redirect from rambina.com to www.rambina.com?

[saurabh]

I have one new site having domain name rambina , which is having around 100 or more pages. But google has indexed rambina.com as well as http://www.rambina.com and so on with other pages too.
I am using Godaddy for hosting as well as for domain account, on the windows server. I have read somewhere here also that .htaccess doesn't work with it.
I have bought an ssl certificate for it few days ago.
Now my question is that can i have only one way or the code clearly written so that if anyone clicks rambina.com/xxxxxxxx/xxxxx or https://www.rambina.com/xxxxx/xxxxx. I need urgent help for it, please provide me the code with the explanation where and how to use or upload it.
