>Environment:
SunOS sif.ttsg.com 5.7 Generic sun4u sparc SUNW,Ultra-1
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.8.1/specs
gcc version 2.8.1
>Description:
2 machines.  DNS used for "load balancing".  When invoking CGI's with
mod_rewrite it would drop information.  Was suggested to be changed from
[R,L] to [P]

Doing so causes:
[Fri Apr 16 12:09:44 1999] [warn] [client 207.99.6.160] handler "cgi-wrapper" not found for: proxy:http://aserver.karupspc.com/lcgi-bin/wwwjoin/signup.cgi
[Fri Apr 16 12:09:44 1999] [error] [client 207.99.6.160] File does not exist: proxy:http://aserver.karupspc.com/lcgi-bin/wwwjoin/signup.cgi

The first message appears on EVERY cgi invocation.  I previously put in a report 
about it but never heard back.
