My question is related to the following:
"Apache not working with user Sites folder on macOS 10.13 High Sierra"
I installed High-Sierra over Sierra, and all my localhost/~username/pages were inaccessible. I restored my backed-up Sierra system. Now I'm wondering if that /etc/apache2 directory would have worked on High-Sierra. It has a 'users' directory with username.conf setups for all the /Users who use this machine, each having their own web-pages in their own Sites, and their own sub-directories in /Library/WebServer/CGI-Executables.
Several wab-pages have <form action> .... </form> structures that send <input name values> to scripts which process them and return web-pages, which may, in turn. be sent back for further processing. In other words, it's a design that allows a continuing dialog. Any thoughts?
