Question

I have a VServer where i have some admin-apps in /var/www/,
an other common stuff in /var/customers/webs/web001/.

I want to make a redirection for all not existing files and directories

            /var/www/ -> /var/customers/webs/web001/

So that i can use the domain-name for root and for web001 customer.

I am not sure what is the best way to achieve this.
I tried with mod_rewrite, but there are internal redirections that reach the Limit of Recursion.

What i am doing wrong?

.htaccess

            # allow psydo-location (not existing folder)
            Options +FollowSymLinks

            # Turn on URL rewriting engine
            RewriteEngine On

            # Folder of this htaccess-file in not root-folder
            RewriteBase /var/www/

            # Disable rewriting for existing files or directories
            RewriteCond %{REQUEST_FILENAME} !-f
            RewriteCond %{REQUEST_FILENAME} !-d
            RewriteCond %{REQUEST_FILENAME} !^/var/customers/webs/web001/

            # redirect all other requests to index.php
            rewriteRule ^.*$ /var/customers/webs/web001/index.php [DPI,L]

Ok. I found a Solution.
It is not in the .htaccess, but in the httpd.conf.
With appropriate settings for DocumentRoot almost all request will be delivered form /var/customers/webs/web001/,
except of these who will be excluded with Alias-Directives.

The /etc/apache2/httpd.conf look something like that:

            #NameVirtualHost SERVER_IP:PORT
            <VirtualHost SERVER_IP:PORT>
                ServerName SERVER_IP
                ServerAlias DOMAIN.TLD

                # instead of DocumentRoot "/var/www/"
                DocumentRoot "/var/customers/webs/web001/"

                # add Aliases for each Application in the /var/www
                Alias /URL_SUB_PATH_APP_1 "/var/www/URL_SUB_PATH_APP_1"
                Alias /URL_SUB_PATH_APP_2 "/var/www/URL_SUB_PATH_APP_2"
            </VirtualHost>

            Include /etc/apache2/vhosts.conf

Like Gerben said, the .htaccess-file is for this purpose not helpful.
