Subject: Re: Checking what a method has returned

I do not know if this will help you out, I think this is what you 
wanted. This only calls the downloadImg method if the file exists.


@domains = ['yahoo.com','google.com']

def checkCache(filename)
  if File.exists?(filename)
    return true
  else
    return false
  end
end

def downloadImg(name)
  puts "called the download function"
end

@domains.each do |domain|
  if checkCache(domain)
    downloadImg(domain)
  end
end
