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, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;chris

class Project \< ActiveResource::Base &nbsp;&nbsp;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.
