i have met a very confusing problem while using Mechanize to submit a  
form with a file return. how should i save the file? thanks a lot for  
any response 🙂

## code here:

url =  
"[http://xxxx.com/abc.aspx?CurDate=2008-12-08&PingID=93761&IPAddress=172.28.33.179](http://xxxx.com/abc.aspx?CurDate=2008-12-08&PingID=93761&IPAddress=172.28.33.179)

## agent = WWW::Mechanize.new {|a| a.log = Logger.new(“mechanize.log”) } p = agent.get(url) form = p.form(“Form1”) agent.submit(form, form.buttons[0])
