dns lookup for reverse proxy

Dear all,

I have the following directives in my conf file.

<ifmodule mod_proxy.c>
proxyrequests off
RewriteEngine On

ProxyPass /Server/ http://localhost:8081
ProxyPassReverse /Server/ http://localhost:8081
RewriteRule ^/Server$ /Server/ [P]
</IfModule>

My error log:
[Wed Sep 22 02:59:41 2004] [error] [client 192.168.1.22] proxy: DNS
lookup failure for: example2 returned by /Server

Does a force proxy requires a dns lookup on the httpd server itself?
When I change from a [P] to a [R], it works but our client does not
understand a http 302 (axis client).

try something like
<ifmodule mod_proxy.c>
ProxyPass /Server/ http://localhost:8081/
ProxyPassReverse /Server/ http://localhost:8081/
</ifmodule>

you shouldn't need the other stuff to make it work

It didn't work, because it's not under the DocumentRoot.
