I was wondering how I could set a custom user-agent for all of my API  
requests from ActiveResource? Basically, I want to identify my  
application when ever I hit someone’s API from ActiveResource.

Thanks!  
Tom

Disclaimer - I haven’t tried this, but it should work:

class Person \< ActiveResource::Base  
self.site = “[http://api.people.com:3000/](http://api.people.com:3000/)”  
self.headers[“User-agent”] = “MyUser/agent v1.0”  
end

ActiveResource::Base#headers returns a hash, so it should be as easy as  
that.
