Hello *,

On my gateway I use a bunch of files (currently 1782) like

----8<------------------------------------------------------
<VirtualHost 88.168.69.36:80>
     ServerName          $HOST_NAME

     ProxyRequests       off
     ProxyVia            on
     ProxyPass           / http://$HOST_IP/
     ProxyPassReverse    / http://$HOST_IP/
     ProxyPreserveHost   on
     <Proxy *>
         Order           deny,allow
         Allow           from all
     </Proxy>
  </VirtualHost>
----8<------------------------------------------------------

and it works perfectly, but i disike the memory consumation of apache2.2
so, my question is:
                         How can I do this better?

With mod_rewrite and rewritemap. It should look something like this (untested):

urlmap.txt [textfile]
host1           ip1
host2           ip2
host3           ip3
.
.
.

httpd.conf:
RewriteEngine On
RewriteMap urlmap txt:/path/to/urlmap.txt
# Only rewrite if there is a host header
RewriteCond %{HTTP_HOST} !^$
# Lowercase the hostheader
RewriteCond ${lowercase:%{HTTP_HOST}} ^(.+)$
# Rewrite only if there is an entry in the urlmap
RewriteCond ${urlmap:%1} ^([0-9].*)$
RewriteRule /(.*) http://%1/$1 [P,L]
