Dynamic subversion repositories through subdomains (in Apache)

Question

I am trying to set up a translation of a subdomain repository in Apache. Example:

foobars.domain.com -> /server/svnrepos/foobars

I tried to do this using mod_rewrite :

RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain\.com$ [NC]
RewriteRule ^/svn(.*) /svn/%2$1 [PT]

However, this causes problems with basic svn operations; "checkout" calls this nice thing:

$ svn co http://foobars.domain.com/svn
svn: '/svn/foobars/!svn/vcc/default' path not found

I have no limitations in terms of server settings (my machines, os, etc.). Is there any way to get this translation processed by Apache? I looked at massive virtual hosts, but I see no way to extend the concept to DAV locations (I would like VirtualSvnPath ...). The way mod_dav_svn forces you to either: 1) explicitly identify your svn repo path, or 2) identify your parent, is very limited.

, "SVNSpecialURI" , ...

, SVNPath, ?

conf :

<VirtualHost *:80 *:443>
    ServerAdmin [e-mail]
    DocumentRoot "/server/www"
    ServerName domain.com
    ServerAlias *.domain.com www.domain.com domain.com
    ErrorLog logs/domain-error_log
    CustomLog logs/domain-access_log common

    DirectorySlash Off

    RewriteLogLevel 9
    RewriteLog /server/log/apache-rewrite.log

    RewriteEngine On
    RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
    RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain\.com$ [NC]
    RewriteRule ^/svn$ /svn/ [QSA]

    RewriteCond %{HTTP_HOST} !^www\.domain\.com$ [NC]
    RewriteCond %{HTTP_HOST} ^(www\.)?([^.]+)\.domain\.com$ [NC]
    RewriteRule ^/svn(.*) /svn/%2$1 [PT]

<Location /svn>
    DAV svn
    SVNParentPath /server/svn
</Location>
