mmmmmm, interesting... but in my server subdomains are in fact sub directories, if I am not wrong...
and the main .htaccess (at public_html) will prevail over the wiki subdirectory...
this is the modx .htacces:
# For full documentation and other suggested options, please see
# http://svn.modxcms.com/docs/display/MODx096/Friendly+URL+Solutions
# including for unexpected logouts in multi-server/cloud environments
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
# Fix Apache internal dummy connections from breaking [(site_url)] cache
RewriteCond %{HTTP_USER_AGENT} ^.*internal\ dummy\ connection.*$ [NC]
RewriteRule .* - [F,L]
# Rewrite domain.com -> www.domain.com -- used with SEO Strict URLs plugin
#RewriteCond %{HTTP_HOST} .
#RewriteCond %{HTTP_HOST} !^example\.com [NC]
#RewriteRule (.*) http://example.com/$1 [R=301,L]
# Exclude /assets and /manager directories from rewrite rules
RewriteRule ^(manager|assets) - [L]
# For Friendly URLs
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
# Reduce server overhead by enabling output compression if supported.
#php_flag zlib.output_compression On
#php_value zlib.output_compression_level 5
and this is the wiki .htaccess:
