Mechanize html scraper

Question

so I'm trying to extract my site's email using ruby ​​mechanization and hpricot. that I'm trying to make my loop on the entire page of my administration and parse pages with hpricot.so so well. Then I get:

Exception `Net::HTTPBadResponse' at /usr/lib/ruby/1.8/net/http.rb:2022 - wrong status line: *SOME HTML CODE HERE*

when it parses a bunch of pages, it starts with a timeout and then prints the html code of the page. I can not understand why? how can i debug this? It seems that the machine operator can get more than 10 pages in a row? Is it possible?? thanks

require 'logger' require 'rubygems' require 'mechanize' require 'hpricot' require 'open-uri'

def initialize(page) @page=page @agent = WWW::Mechanize.new{|a| a.log = Logger.new("logs.log") } @agent.keep_alive=false @agent.read_timeout=15

end

def login f = @agent.get( "http://****.com/admin/index.asp") .forms.first f.set_fields(:username => "user", :password =>"pass") f.submit
end

def harvest(s) pageNumber=1 #@agent.read_timeout = s.upto(@page) do |pagenb|

        extract(pagenb)

    rescue => e
        puts  "unknown #{e.to_s}"
        #puts  "url:http://****.com/admin/members.asp?action=search&term=&state_id=&r=500&p=#{page}"

        puts "mechanize error: "+ex.response_code
