I am trying to do this same thing here but with Ruby: Access Authenticated GAE Client with Python. Any ideas how to retrieve authenticated content from GAE with Ruby?

I am using the Ruby GData Gem to access everything in Google Docs and such and it's making life very easy, but now I'd like to access things on GAE that require admin access, programmatically, and it doesn't support that.

Here's what I'm getting (using DocList, not sure what to use yet):

c = GData::Client::DocList.new
c.clientlogin(username, password, nil, nil, nil, "HOSTED")
c
=> #<GData::Client::DocList:0x201bad8 @clientlogin_service="writely", @version="2",
  @auth_handler=#<GData::Auth::ClientLogin:0x200803c @account_type="HOSTED",
  @token="long-hash", @auth_url="https://www.google.com/accounts/ClientLogin",
  @service="writely">, @source="AnonymousApp", @headers={"Authorization"=>"GoogleLogin
  auth=long-hash", "User-Agent"=>"GoogleDataRubyUtil-AnonymousApp",
  "GData-Version"=>"2", "Content-Type"=>"application/atom+xml"},
  @authsub_scope="http://docs.google.com/feeds/",
  @http_service=GData::HTTP::DefaultService>

url = "http://my-cdn.appspot.com/files/restricted-file.html"
c.get(url)
=> #<GData::HTTP::Response:0x20004b8 @status_code=302, @body="",
  @headers={"connection"=>"close", "date"=>"Sun, 11 Apr 2010 00:30:20 GMT",
  "content-type"=>"text/html", "server"=>"Google Frontend", "content-length"=>"0",
  "location"=>"https://www.google.com/accounts/ServiceLogin
  service=ah&continue=http://my-cdn.appspot.com/_ah/login%3Fcontinue%3D
  http://my-cdn.appspot.com/files/restricted-file.html&
  ltmpl=gm&ahname=My+CDN&sig=a-signature"}>

Any tips? That other SO question pointed to doing something with the redirect... Not sure how to handle that.

Just looking for a point in the right direction from the ruby experts. Thanks.
