Re: [PLUG] Apache Mod Proxy & Mod Rewrite Questions

[Jason Stelzer <jason.stelzer@gmail.com>]

back when I was using mongrel clusters for my rails apps, I would set
up something along the lines of this:

#    ProxyRequests Off
#    ProxyPreserveHost On
#    RewriteEngine On
#    <proxy *>
#      order deny,allow
#      allow from all
#    </proxy>
#    RewriteRule ^/(.*)$ balancer://myapp1/$1 [P,L]
#
#   <Proxy balancer://myapp1>
#       BalancerMember http://127.0.0.1:3000
#       BalancerMember http://127.0.0.1:3001
#       BalancerMember http://127.0.0.1:3002
#       BalancerMember http://127.0.0.1:3003
#       BalancerMember http://127.0.0.1:3004
#   </Proxy>

Just not that you define a rewrite rule for everything under the web
root. Then you define what to write it to. I was using balancers
because mongrel is a single ruby process per port. So i was round
robin load balancing.

Note that blancer://myapp1 is defined, and the members are named in
the definition.

For your purposes you could probably just use
http://www.newsite.com/$1 [P,L] and it'll just go.
