My “argument” is only because I see so many people suffering needlessly while trying to use Codex info that does not address every possible server scenario…and I did not just say it could not be made to work in every scenario. Rather, I am only saying the Codex is not always needed or this would never work:
## from https://my.bluehost.com/cgi/help/347#redirect
# .htaccess main domain to subdirectory redirect
# Do not change this line.
RewriteEngine on
# Change example.com to be your main domain.
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
# Change 'subdirectory' to be the directory you will use for your main domain.
RewriteCond %{REQUEST_URI} !^/subdirectory/
# Don't change the following two lines.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Change 'subdirectory' to be the directory you will use for your main domain.
RewriteRule ^(.*)$ /subdirectory/$1
# Change example.com to be your main domain again.
# Change 'subdirectory' to be the directory you will use for your main domain
# followed by / then the main file for your site, index.php, index.html, etc.
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
#RewriteRule ^(/)?$ subdirectory/index.html [L]
## index.php for WordPress
RewriteRule ^(/)?$ subdirectory/index.php [L]
I can place any of my WordPress installations in any folder of any name while doing nothing more than assigning its domain name (mysite.com) to that location and WordPress works perfectly. Maybe you have never done that or have never had the opportunity or desire or willingness to try it or whatever, but you absolutely cannot show that to be wrong information.
