net/http with cookies?

I'm attempting to navigate a website that requires a login. In
particular, does anyone have a solution that utilizes cookies? Looking
at the included Net/http library, it doesn't appear to be supported - or
at least it isn't mentioned. Thanks in advance!

Hi Brian,

I assume when you've logged in, your details are saved
in the cookie and you bypass the next login by providing
the saved cookie.

A cookie is sent as a Hash value ['Cookie'] in the headers
along with the request and received as a Hash value with
a key of ['Set-Cookie'] along with the response.

The snippet below will obtain a cookie from google
as a non-login example.
The commented hdrs['Cookie'] = 'blah' is where you
would provide a previously saved cookie.

More information than you need about cookies here:
[HTTP State Management Mechanism]
http://www.faqs.org/rfcs/rfc2109.html

Hope that's enough to get you going.

cookie = resp['Set-Cookie']
if cookie
puts cookie.split(/;/)
puts '-----', resp.body
else
puts 'No cookie received'
end

puts "Error - code(#{resp.code}) - #{resp.msg}"
end
