Subject: Re: NoMethodError split for array using optional parameter

Thanks robert. I'll spend some time thinking about what you wrote. When 
I learn about OOP, perhaps that will help, too.
So you know, this is the method I 'ended up' with:

def cookies(*args) #If a value is passed, it is added to cookies, else 
cookies are returned.
  $cookiesH = {} if $cookiesH == nil
  #adds cookies to cookies hash
  if (args[0] != nil) then
      if (args[0].is_a? Array) then c = args[0].join(";") else c = 
args[0].to_s end
    c.split(";").each {|e|
      e.match(/(.*)=(.*)/)
      key = $1.strip   unless $1 == nil
      k = key.downcase unless $1 == nil
      if ($2 != nil and $1 != nil and k != "expires" and k != "max-age" 
and k != "domain" and k != "path") then
        $cookiesH[key]=$2
      end
      }
  end

  #reports cookies in string format
  if (args[0] == nil) then
    cookies = $cookiesH.map{|k, v| "#{k}=#{v}"}.join("; ")
    return cookies
  end
end
