I’m doing some route hacking and have run into something I haven’t  
been able to get past. I need to add a custom condition on to RESTful  
resources in the same way that you can add custom conditions to other  
routes. I have already hacked on my solution for most routes by  
chaining to recognition\_conditions, but the conditions seem to be  
ignored by RESTful routes.

The desired behavior would be to pass a :conditions =\> {:subdomain =\>  
true/false} and have that run a logic check to see whether the  
subdomain of the current host matches against a list of allowed  
subdomains. I have the logic, it works fine for most routes, but I  
can’t see how to add conditions to the RESTful routes since they  
aren’t picked up by the rest.

Any help would be appreciated.

Thanks,
