Hi,

I’m using the ActiveResource (beta) gem. I need to change the header  
fields for the request.  
There is “default\_header” in ActiveResource::Connection which is  
“Content-type: application/xml”. I do not see how to change that.  
Could someone give me a hint.

TIA & regards,  
chris

class Project \< ActiveResource::Base  
headers[‘X-Token’] = ‘foo’  
end

Adds the X-Token header to all requests.

Thank you for your help. The “headers” methods isn’t yet included in  
the ActiveResource gem. However, due to your hint, I downloaded at the  
SVN sources and it works.
