I thought that mechanize follows redirection by default … by my script ends at the redirection page. How can I handle this?

require 'rubygems'
require 'mechanize'

agent = WWW::Mechanize.new 

page = agent.get("http://www.vbulletin.org/forum/index.php")

login_form = page.form_with(:action => 'login.php?do=login')

login_form['vb_login_username'] = 'user name'
login_form['vb_login_password'] = ''
login_form['vb_login_md5password_utf'] = 'md5 hash from the password'
login_form['vb_login_md5password'] = 'md5 hash from the password'

page = agent.submit login_form

#Display welcome message if logged in
puts page.parser.xpath("/html/body/div/table/tr/td[2]/div/div").xpath('text()').to_s.strip

output = File.open("login.html", "w") {|f| f.write(page.parser.to_html) }

    Are you sure it’s HTTP 30x Redirect response? Not normal “200 OK” response with page containing <meta http-equiv="refresh" content="100;url=...">. Mechanize follows first type of redirection, second is just normal response with link, which you should follow.

    I can’t check, because you didn’t posted username/password in code.

    Edit:
    After your update, this should be enough to follow redirection after login:

    page.link_with(:text => "Click here if your browser does not automatically redirect you.").click
