.htaccess - domain to directory rewrite, duplicate website problem. - Apache Web Server forum at WebmasterWorld

I have 3 domains: xyz1.com, xyz2.com and xyz3.com (all with cnames www.) to be delivered from the same virtual server.

Home directory for the server is /home/user1/htdocs

Home directories for the 3 domains are:

xyz1.com: /home/user1/htdocs
xyz2.com: /home/user1/htdocs/xyz2
xyz3.com: /home/user1/htdocs/xyz3

Shared directories for the websites are icons, cgi-bin and images.

Using /home/user1/htdocs/.htaccess I manage to hide the xyz2 and xyz3 directories from the url's:

ErrorDocument 404 [xyz1.com...]
RewriteEngine on
Options +FollowSymlinks
RewriteBase/

# allow access to shared directories
RewriteCond %{REQUEST_URI} ^/icons/.* [OR]
RewriteCond %{REQUEST_URI} ^/images/.* [OR]
RewriteCond %{REQUEST_URI} ^/cgi-bin/.*
RewriteRule ^(.*)$ $1 [L]

# prevents external access to xyz2 and xyz3 directories from host ip, none or xyz1.com
RewriteCond %{REQUEST_URI} ^/xyz2/.* [OR]
RewriteCond %{REQUEST_URI} ^/xyz3/.*
RewriteCond %{HTTP_HOST} ^$ [OR]
RewriteCond %{HTTP_HOST} ^123\.123\.123\.123$ [OR]
RewriteCond %{HTTP_HOST} xyz1\.com$ [NC]
RewriteRule ^(.*)$ $1 [G]

# prevents external access to xyz2 directory from host xyz3.com
RewriteCond %{REQUEST_URI} ^/xyz2/.*
RewriteCond %{HTTP_HOST} xyz3\.com$ [NC]
RewriteRule ^(.*)$ $1 [G]

# prevents external access to xyz3 directory from host xyz2.com
RewriteCond %{REQUEST_URI} ^/xyz3/.*
RewriteCond %{HTTP_HOST} xyz2\.com$ [NC]
RewriteRule ^(.*)$ $1 [G]

# missing trailing / for directory problem
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+[^/])$ $1/[R]

# redirect xyz2.com to xyz2
RewriteCond %{HTTP_HOST} xyz2\.com$ [NC]
RewriteCond %{REQUEST_URI}!^/xyz2/.*
RewriteRule ^(.*)$ /xyz2/$1 [L]

# redirect xyz3 to xyz3
RewriteCond %{REQUEST_URI}!^/xyz3/.*
RewriteCond %{HTTP_HOST} xyz3\.com$ [NC]
RewriteRule ^(.*)$ /xyz3/$1 [L]

A call to [xyz2.com...] now returns the document /home/user1/htdocs/xyz2/index.html

However, [xyz2.com...] returns the same document, resulting in possible search engine penalties for duplicating websites.

I wish to remove [xyz2.com...] as a valid url, but all my attempts so far has resulted in a rewrite looping problem:

RewriteCond %{HTTP_HOST} xyz2\.com$ [NC]
RewriteCond %{REQUEST_URI} ^/xyz2/.*
RewriteRule ^(.*)$ $1 [G]

I have tied NS, N, C, L and S but have not managed to achieve the desired effect with my attempts.

Any and all suggestions and/or hints are greatly appreciated (also regarding more efficient code on what is already working)!

.htaccess - domain to directory rewrite, duplicate website problem.

Disallowing direct browser access to directories but allowing rewrite.
