I am able to login to a website at [authenticate.domain.com](http://authenticate.domain.com) but when I  
attempt to visit [panel.domain.com](http://panel.domain.com) it appears the http session has been  
lost.

Code:  
Net::HTTP.start(‘[authenticate.domain.com](http://authenticate.domain.com)’,80){|http|  
log = http.post(‘script.php’,params)  
puts log.body  
}

```
            Net::HTTP.start('panel.domain.com',80){|http|
                    puts http.get('/index.cfm').body
            }

```

So, what could be the problem? Either the second Net::HTTP.start call is  
beginning a new session or the first call is forgetting a vital cookie.  
Anyone? Thanks!

In your code you are basically getting the body of the response only.  
Session or cookie information should be in the header… Basically in  
a Net::HTTPResponse object you have the Net::HTTPHeader mixed in. Try  
looking at the both api’s and you’ll see it clearly…

Cheers,

Ok, great. After doing some studying I understand a bit more now. Thank  
you!

I’ve got my script logging in but the session still doesn’t persist. I  
auto-follow a few redirects and I end up back where I was (not logged  
in).

I did notice Net::HTTP’s get\_fields(‘set-cookie’).

Do I need to use set\_content\_type(‘set-cookie’,@@cookie)? where @@cookie  
= get\_fields(‘set-cookie’) # of the first login attempt?

Oh. Then what does get\_fields(‘set-cookie’) do?

Net::HTTP doesn’t save your cookies. If you’d like to have your cookies  
automatically saved between each request, check out WWW::Mechanize.
