Python mechanize在页面加载时卡住，直到超时，而常规浏览器工作正常，没有javascript/ajax

使用python和mechanize，我正在尝试登录网站

我使用的代码是：

    from mechanize import Browser

def calOnline(uname,passwd):
    br = Browser()
    br.set_debug_http(True)
    br.set_debug_redirects(True)  
    br.set_debug_responses(True)
    br.set_handle_redirect(True)
    br.set_handle_robots(False)
    br.set_handle_refresh(True)
    #~ br.encoding()
    br.addheaders = [('User-Agent','Mozilla/5.0 (X11; Linux x86_64; rv:13.0) Gecko/20100101 Firefox/13.0.1'),
        ('Accept','text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'),
        ('Accept-Language','en-us,en;q=0.5'),
        ('Accept-Encoding','gzip, deflate'),
        ('Connection','keep-alive')]
    print('opening site')
    br.open('https://m.cal-online.co.il/')
    print('\n\nsubmiting first form')
    br.select_form(nr=0)
    br.submit()
    print('\n\nselecting login form')
    br.select_form(nr=0)
    br['ctl00$cphMain$LGN$UserName'] = uname
    br['ctl00$cphMain$LGN$Password'] = passwd
    print('\n\nsubmitting form')
    br.submit(name='ctl00$cphMain$LGN$LoginButton')
    print('\n\nOpening details page')
    res = br.open('https://m.cal-online.co.il/SCREENS/Transactions/TrSearch.aspx')
    print res.read()


uname = 'someuname'
passwd = 'somepasswd'   
a = calOnline(uname, passwd)
print a.read()

该网站是移动版的信用卡网站，我试图从中获得我的费用

浏览器（Android手机版或Firefox/Chrome/Opera桌面版）打开站点并登录，没有任何问题。 尝试以编程方式登录时，它卡住了，下面是iOS用户代理的调试日志：
