Are two implementations necessary? Isn't setting COOKIE_FILE good enough for
this to work on app engine without any additional differences?

[stgao, 2014/08/15 23:11:03]

Yes, we need two different implementation.
On appengine, we don't have to sending cookie at all. The app is whitelised.

And we won't use urllib2. We will use url_fetch.
