Thanks Richard.
I'm just using the render json option in Rails. I don't know how to
query header contents.
Using curl I get:
HTTP/1.1 200 OK
Etag: "c420691e7608d694896d67415bec23d7"
Connection: Keep-Alive
Content-Type: application/json; charset=utf-8
Date: Thu, 16 Sep 2010 09:51:10 GMT
Server: WEBrick/1.3.1 (Ruby/1.8.7/2010-01-10)
X-Runtime: 114
Content-Length: 2062
Cache-Control: private, max-age=0, must-revalidate
This is the header right?
What do I need to do with this?
