Apache plugin settings WLLogFile and WLTempDir ignored

 I have made several attempts to set these to use a different location, running the Apache plugin (mod_wl_22.so) running on Apache 2.2.3 RHEL 5.8. Here is my config, as reported by server-info module:

Debug ON

DebugConfigInfo ON

WLLogFile /var/log/httpd/mod_weblogic_log

Idempotent ON

<VirtualHost LWB00717:80>

   <Location /console>

     WebLogicHost 10.192.91.15

     WebLogicPort 7001

   </Location>

   <Location /consolehelp>

     WebLogicHost 10.192.91.15

     WebLogicPort 7001

   </Location>

</VirtualHost>

The plugin is still logging to /tmp/wlproxy.log, and even when I changed WLTempDir my change was ignored. Any suggestions?
