rewriting problem in reverse proxy scenario

["Quartex Quartex" <quartex73@xxxxxxxxx>]

Hi list,
to the point:  reverse proxy http to https for Lotus Quickplace:


ProxyRequests Off
ProxyPreserveHost Off
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/sequick.pippo.it.crt
SSLCertificateKeyFile /etc/apache2/ssl/sequick.pippo.key
ProxyPass /QuickPlace http://sequick.pippo.it/QuickPlace
ProxyPass /icons http://sequick.pippo.it/icons
ProxyPass /qphtml http://sequick.pippo.it/qphtml
ProxyPass /bacheca http://sequick.pippo.it/bacheca
ProxyPass / http://sequick.pippo.it/QuickPlace/
ProxyPassReverse / http://sequick.pippo.it
<Location />
RewriteEngine On
RedirectMatch 301 ^/$ /QuickPlace/quickplace/Main.nsf?OpenDatabase\&Login
RewriteRule ^/QuickPlace/([^/]+)/? /QuickPlace/$1/Main.nsf
SSLRequireSSL
Allow from all
</Location>

Explanations:
Static Reverse for /QuickPlace /icons /qphtml /bacheca
Dynamic Reverse for /  so every links like this

http://sequick.pippo.it/testis proxied to

https://sequick.pippo.it/QuickPlace/test.
 need to add /Main.nsf too after https://sequick.pippo.it/QuickPlace/test
and this is the only thing that I was not able to make working.
RewriteRule doesn't seem to work...
Any suggestions?
Thanks
