Hi John,
It shouldn't be a problem. We actually do not "detect" the domain name. We read it directly from the Url address that the user typed in. For examle, if your user typed this in the browser:
http://www.some_domain_name.com/WebForm1.aspxWe will see "some_domain_name.com" as the domain name and check whether this domain name matches the domain name that you used to create the key. If it does not match, then a license error is shown.
Hope this clears up. Please feel free to reply if you still have more questions.
Thanks
