SCM-Server and Apache mod_proxy

Question

I try to hide the SCM-Manager behind Apache 2.4.

The Apache is listening on

http://192.168.2.102

and the SCM is listening on

http://192.168.2.102:8080

Following this description I am able to access the management interface of SCM server through Apache. With this mod_proxy configuration

<VirtualHost 192.168.2.102:80>
    RewriteEngine on
    <Location /scm>
        ProxyPass http://192.168.2.102:8080/scm connectiontimeout=5 timeout=30
        ProxyPassReverse http://192.168.2.102:8080/scm
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>

I can also check out my repository.

By adding this mod_rewrite rule

RewriteRule ^/svn/(.*)$ /scm/svn/$1 [P]

my intention was to permit the access to my repo via

http://192.168.2.102/svn/REPO

But at check out with

svn co http://192.168.2.102/svn/aaa aaa

I get this error:

svn: E175002: svn: E175002: E175002: Invalid URL 'http://192.168.2.102:8080/svn/aaa' requested

What else should I set for the rewrite module to serve me the repo just with the /svn/REPO URI?
