? Not sure why you're trying to use mod_rewrite here.

Your VirtualHost can include something like this:

  ProxyPass /service/ balancer://service_cluster/   ProxyPassReverse /service/ balancer://service_cluster/      ProxyPass / balancer://default_cluster/   ProxyPassReverse / balancer://default_cluster/      <Proxy balancer://default_cluster>           BalancerMember http://localhost:4000           BalancerMember http://localhost:4001           BalancerMember http://localhost:4002   </Proxy>

  <Proxy balancer://service_cluster>           BalancerMember http://localhost:4010           BalancerMember http://localhost:4011           BalancerMember http://localhost:4012   </Proxy>

Add: ActionController::AbstractRequest.relative_url_root = "/service" ::to your /service/ environment.rb and you should be set.

Or at least it seems to work for me :slight_smile:

FWIW,

Thanks Hassan. I still get the same error though! :confused: My vhosts.conf looks like this now:

<VirtualHost *:80>     ServerName myapp.com     ServerAlias www.myapp.com   ServerAlias myapp     DocumentRoot "C:/dev/server/app/myapp/public"

  ProxyPass / balancer://myapp_cluster/   ProxyPassReverse / balancer://myapp_cluster/

  ProxyPass /service/ balancer://myapp_service_cluster/   ProxyPassReverse /service/ balancer://myapp_service_cluster/

  <Directory "C:/dev/server/app/myapp/public">     Options FollowSymLinks     AllowOverride None     Order allow,deny     Allow from all   </Directory>

  <Directory "C:/dev/server/app/myapp_service/public">     Options FollowSymLinks     AllowOverride None     Order allow,deny     Allow from all   </Directory> </VirtualHost> <Proxy balancer://myapp_cluster>   BalancerMember http://localhost:4000   BalancerMember http://localhost:4001   BalancerMember http://localhost:4002 </Proxy> <Proxy balancer://myapp_service_cluster>   BalancerMember http://localhost:4010   BalancerMember http://localhost:4011   BalancerMember http://localhost:4012 </Proxy>

The relative_url_root thing was put into the /service/ environment.rb.

About the rewrites, one reason IIRC is to allow Apache to handle the static content? Whether or not my rewrites actually do that is another question. :wink:

I've also tried, in the root application public/.htaccess file, to do:

# If you don't want Rails to look in certain directories, # use the following rewrite rules so that Apache won't rewrite certain requests

Thanks Hassan. I still get the same error though! :confused: My vhosts.conf looks like this now:

        ProxyPass / balancer://myapp_cluster/         ProxyPassReverse / balancer://myapp_cluster/

        ProxyPass /service/ balancer://myapp_service_cluster/         ProxyPassReverse /service/ balancer://myapp_service_cluster/

I think the order of the above is significant -- the more specific reference should come first, because anything will match to /.

Have you looked at your mongrel logs? I'm betting the Routing Error is coming from a mongrel in your my_app cluster, /not/ the myapp_service_cluster.

</VirtualHost> <Proxy balancer://myapp_cluster>   BalancerMember http://localhost:4000   BalancerMember http://localhost:4001   BalancerMember http://localhost:4002 </Proxy> <Proxy balancer://myapp_service_cluster>   BalancerMember http://localhost:4010   BalancerMember http://localhost:4011   BalancerMember http://localhost:4012 </Proxy>

BTW, I think the Proxy elements should be inside the VirtualHost element, though that's probably not the cause of this problem...

About the rewrites, one reason IIRC is to allow Apache to handle the static content?

Ah, well, that's totally different. I never do apps with enough static content to bother :slight_smile:

But I would try swapping the ProxyPass stuff first...

HTH,

Well that helped. =) Probably because of the order like you said.

The routing error would've had to be in the root app since I haven't had a /service/ app running most of the time. :wink:

Adding the rewrites again underneath, it reverts back to the old behaviour, but this isn't being deployed for another couple of months so I think I'll drop it for now.

Thanks again!, Bjørn
