CKFInder License

Hello,

We want to integrate CKFInder with FCKEditor which we are currently using in an ASP.Net Web Application, so we want to purchase CKFinder License. We have one URL but it includes three environment i.e Dev,Demo and Prod . So which License we should go for. Whether it will be for One Website License or Corporate Website License?

Will the single Website License is good enough and will it cover all three environments within one URL?

Please let me know,so that i can update my manager and move accordingly.

Is there any other contact information so that i contact you regarding this?

Thanks,
Phanish.
