I will need a go based solution, not at the container level
the container is suppose to mount volume and there is no reason it will be on /usr/share/httpd

1- first fix the infinte loop in the correct function, if index.html request a redirection because file is missing then we need to show an internal server error 500
2- when the server starts verify that index.html exists before starting

/usr/share/httpd it's a hardcoded root for serving files.

Added server startup check if index.html exists. Without mounted httpd folder server won't start because of lack of index.html file. So this only possible solution for now

Added 404 page not found error if file do not exists.
