Framesets cannot be previewed when the testing server is remote

(TechNote) View > Live Data, or Preview In Browser, do not function if the Testing Server category of the Dreamweaver site definition is set to anything but “none”. Depending on what types of pages you have in your frameset, you will see one of these two warnings pop-up in Dreamweaver when you try to go into Live Data view or Preview In Browser.

If you run Preview in Browser on a frameset, then this message displays:

Framesets cannot be previewed when the testing server is remote. Would you like to preview the frameset locally?

If your frameset consists of server-side files (e.g. ASP files) and you run View > Live Data, then this message displays:

The testing server did not execute any of the scripts in your document. Possible explanations include:

1) The testing server is not running.
2) The testing server ignores files with the “.asp” file extension.
3) Your document does not contain any scripts.
