I’m having trouble with mapping a first domain to:

```
map.connect ':action', :controller => 'admin'

```

I can get that to work, and I’d be fine if there’s only one domain  
pointing to my app.

However, I will point several domains to the app, so I only want that  
route for one domain.

I’ve tried:

```
map.connect ':action', :controller => 'admin' if @request.host == 

```

‘[domain.com](http://domain.com)’

but I get an error about nil.host. I’m not sure but it seems @request  
is undefined in routes.rb.

How might I get this done?

Thanks,  
Bill

Hello Bill,

You should take a look at the Rails “Request Routing” plugin  
mentioned in the following post:  
[http://weblog.rubyonrails.org/articles/2006/05/22/dan-webbs-request-](http://weblog.rubyonrails.org/articles/2006/05/22/dan-webbs-request-)  
routing-plugin

It looks like it will fullfill your need.

That looks good. A little more digging reveals routes.rb is set once,  
before @request is set.

The plugin is a nice work around.

Thanks,
