HTTP_REFERER + apache + mongrel_cluster

Rails Deployment
1

Hi, I’m using configuration Apache 2.2 + Mongrel cluster
and I can not obtain information in my Rails app from
@request.env[“HTTP_REFERER”]

Does anybody know how to setup apache.conf to pass http referer to
mongrel cluster.
This works for webrick but not in Apache+mongrel_cluster configuration.

This is my current apache conf.

<VirtualHost 192.168.1.5>
ServerName domain.com
#NameVirtualHost domain.com
ServerAlias www.domain.com

DocumentRoot /var/www/apps/domain.com/current/public

I use utf-8 for all my projects, so I force apache to send the good

charset by default.

This is needed if you use page caching and want apache serves these

with the good charset.

AddDefaultCharset utf-8

Do not allow open proxying, allow only requests starting with a /

<LocationMatch “^[^/]”>
Deny from all

Avoid open you server to proxying

ProxyRequests Off

Let apache pass the original host not the ProxyPass one

ProxyPreserveHost On

<Directory /var/www/apps/lovcicen_frontend/current/public>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all

Configure mongrel_cluster

<Proxy balancer://lovcicen_frontend_cluster>
BalancerMember http://127.0.0.1:8005
BalancerMember http://127.0.0.1:8006

RewriteEngine On

It’s not exactly the answer you need, but I had to figure out something
similar for REMOTE_USER and eventually ended up with:

            RewriteEngine On
            RewriteCond %{LA-U:REMOTE_USER} (.+)
            RewriteRule . - [E=RU:%1]
            RequestHeader add X-Forwarded-User %{RU}e

So replace REMOTE_USER with HTTP_REFERER and X-Forwarded-User with
X-Forwarded-Referer (or whatever).

You may not even need to get this fancy, as REMOTE_USER is somewhat
special
and you need some extra mod_rewrite voodoo to get it early enough.

Your app will need to be able to deal w/ either
@request.env[“HTTP_REFERER”]
or @request.env[“HTTP_X_FORWARDED_REFERER”]
