Hi,

I’m trying to make cartographer/google maps work with an apache2/  
mongrel setup.

It works fine with lighttpd/fastcgi, however maps don’t render with  
the above setup.

I was wondering if anyone had any success trying this.

Here is what my mongrel configuration file looks like:

## \<\<-=======================================

# cwd: /home/paulm/rails\_apps/myapp/current port: “10011” environment: staging address: localhost #127.0.0.1 pid\_file: log/mongrel.pid servers: 1

and my apache2 config:

\<\<-=======================================  
\<VirtualHost \*:80\>  
ProxyPreserveHost On  
ProxyPass / [http://localhost:10010/](http://localhost:10010/)  
ProxyPassReverse / [http://localhost:10010/](http://localhost:10010/)  
ServerName [my.domain.net](http://my.domain.net)  
#Fix for Apache bug 39499  
SetEnv force-proxy-request-1.0 1  
SetEnv proxy-nokeepalive 1

Listen localhost:10010  
  
ServerName [my.domain.net](http://my.domain.net)  
DocumentRoot /home/paulm/rails\_apps/myapp/current/public

\<Directory “/home/paulm/rails\_apps/myapp/current/public”\>  
Options FollowSymLinks  
AllowOverride None  
Order allow,deny  
Allow from all

Include /home/paulm/rails\_apps/myapp/current/config/  
mongrel\_cluster/common.conf

# \<Proxy balancer://mongrel\_cluster\> BalancerMember [http://localhost:10011](http://localhost:10011)

I registered an api key for my domain put in the cartographer config  
file, restarted the mongrel cluster and httpd and I get this when  
looking at the produced html:

\<\<-=======================================

=======================================

As a side note, I tried out this configuration:

## \<\<-=======================================

# cwd: /home/paulm/rails\_apps/myapp/current port: “10011” environment: staging pid\_file: log/mongrel.pid servers: 1

with a registered api key “[my.domain.net:10011](http://my.domain.net:10011)”, and bypassing  
apache2 works.

So, I’m wondering if I’m missing some apache2 configuration magic here!

TIA,  
Paul

The problem is with cartographer. When it tries to lookup the api  
key, it uses HTTP\_HOST in the request. In this setup, its the mongrel.

Here is the fix for vendor/plugins/cartographer/lib/cartographer/  
header.rb:

# \<\<=== def self.header\_for(request, version=2) mh = self.new mh.version = version #uri = request.request\_uri #uri = uri[0…uri.rindex(’/’)] if uri.rindex(’/’) \< uri.length mh.uri = request.env[‘HTTP\_X\_FORWARDED\_HOST’].split(’,’)[0] rescue request.env[“HTTP\_HOST”] #+ uri mh.to\_s end
