Problems with rewrite mode after the first level

[claussit]

Hello ,
(ISPCP 1.0.7 on Ubuntu 10.04 LTS)
I have a problem setting the apche . After the first level, rewrite mode is not working.
In settings / etc/apache2/sites-available/ispcp.conf rewrite mode looks like this:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^LWP::Simple
RewriteRule ^/.* http://%{REMOTE_ADDR}/ [L,E=nolog:1]
</IfModule>

Configuration for my domain is set AllowOverride All .
Php is OK .
I do not understand why the rewrite module does not work after the first level. Can anyone help me please?
