I'm connecting to a web site, logging in.

The website redirects me to new pages and Mechanize deals with all cookie and redirection jobs, but, I can't get the last page. I used Firebug and did same job again and saw that there are two more pages I had to pass with Mechanize.

I took a quick look at the pages and saw that there is some JavaScript and HTML code but couldn't understand it because it doesn't look like normal page code. What are those pages for? How they can redirect to other pages? What should I do to pass these?

If you need to handle pages with Javascript, try WATIR or Selenium - those drive a real web browser, and can thus handle any Javascript. WATIR Classic requires either IE or Firefox with a certain extension installed, and you will see the pages flash on the screen as it works.

Your other option would be understanding what the Javascript on the offending page does and bypassing it manually, but that seems onerous.
