Yes , I read that post , and it sounds like it would work for the shebang issue.
The issue that requires the script alias is the simple issue of calling the script from any .html page. On my remote server the scripts are contained in /cgi-bin/ in the site folder. On xampp the cgi-bin is under the server folder and would require a different reference. One that I would have to change before uploading. So even under /htdocs I would need the script alias, or have to change my script calls on the remote server for each page that has one.
