The Server address and Scripts directory text boxes are combined to make the fully qualified web address. For example:
Server address : www.raosoft.com
Scripts directory : scripts/
The fully qualified web address would be http://www.raosoft.com/scripts/.
When the web server is on the local network (or your computer), the Directory in which to place uploads should be the full path to the Scripts directory, starting with the appropriate network drive letter.
When the web server is on the internet (or not directly accessible on the network) the Directory in which to place uploads can be set to anything. After the publishing files are created, they will need to be transferred via FTP to the web server.
See Web Site Configuration for detailed information on the Web site configuration window.
