Mechanize - follow or "click" meta updates in rails

I have some problems with Mechanize.

When submitting a form using Mechanize. I came to a page with one meta update and there are no links.

My question is: how can I keep track of meta updates?

I tried to enable meta refresh, but then I got a socket error. Code example

require 'mechanize'
agent = WWW::Mechanize.new
agent.get("http://euroads.dk")
form = agent.page.forms.first
form.username = "username"
form.password = "password"
form.submit
page = agent.get("http://www.euroads.dk/system/index.php?showpage=login")
agent.page.body

Answer:

<html>
 <head>
   <META HTTP-EQUIV=\"Refresh\" CONTENT=\"0;URL=index.php?showpage=m_frontpage\">
 </head>
</html>

Then I try:

redirect_url = page.parser.at('META[HTTP-EQUIV=\"Refresh\"]')[
  "0;URL=index.php?showpage=m_frontpage\"][/url=(.+)/, 1]

But I get:

NoMethodError: Undefined method '[]' for nil: NilClass
