mod_rewrite does not work with apache13-modssl and enabled modaccel

[Thomas]

Hello

I compiled apache13-modssl with WITH_APACHE_MODACCEL=YES.
With enabled MODACCEL my mod_rewrite does not work as expected. I get
this error message:
[error] [client xxx.xxx.xxx.xxx] attempt to make remote request from
mod_rewrite without proxy enabled: proxy:http://mysite/foobar/traffic

System: Freebsd 4.11
Apache13-modssl port from 1. August 2006
ssl_config.include:
<IfModule mod_proxy.c>
        ProxyRequests Off
        RewriteRule ^/login/foobar/monitor/(.*)$
http://mysite/foobar/traffic/$1 [P,L]
        ProxyPassReverse /login/foobar/monitor/
http://mysite/foobar/traffic/
</IfModule>

I rebuilded apache13-modssl without MODACCEL and then everything works
perfectly. So i doubt that's a config error. Is this a known behavior?

regards,
Thomas
