The more I research this, the more it looks like I would have to
reset the DocumentRoot dynamically... and so far, that doesn't seem
possible. I've tried the following all of the following directives
in my .htaccess file (one at a time):
php_value doc_root /var/www/domain.com/sub
php_value user_dir domain.com/sub
DocumentRoot /var/www/domain.com/sub
<Directory /var/www/domain.com/sub>
DocumentRoot /var/www/domain.com/sub
</Directory>
<Location />
DocumentRoot /var/www/domain.com/sub
</Location>
<IfModule mod_userdir.c>
UserDir domain.com/sub
</IfModule>
The PHP ones are ignored. All the rest give Internal Server errors.
It seems that PHP used to allow setting doc_root and user_dir
in .htaccess but that was a bug and was fixed years ago. Alas.
It's looking like the only way to set the DocumentRoot or UserDir is
to do so in the system level httpd.conf. Am I missing anything, here?
