Here is the ruby program I'm trying to run, and the Java Program that
explains what I am trying to do a little better.



require 'net/http'
		url = URI.parse("http://localhost/test/scott.jsp")
    req = Net::HTTP::Post.new(url.path)
    req.set_form_data({'test'=>['1','2']})
    res = Net::HTTP.new(url.host, url.port).start {|http|
http.request(req) }
    case res
    when Net::HTTPSuccess, Net::HTTPRedirection
      xml = res.body
    else
      res.error!
    end
		puts xml


Here is the java jsp i'm testing it with.

<%
StringBuffer sb = new StringBuffer();
String[] values = request.getParameterValues("test");
sb.append(values.length + " ");
for(int i=0;i<values.length;i++)
	sb.append(values[i] + " ");
%>
<%=sb.toString()%>

I would expect values to be an array with 2 items in it.

When I run the program I get back a single value with "12" in it.
instead of 2 separate values with "1" and "2" in them.

The query string in the browser would look like "http://localhost/test/
scott.jsp?test=1&test=2"
But i'd like to do that in ruby with a post request.

Thanks for the help.
