Subject: maybe I don't understand the .to_a method...

Hey folks,

I'm attempting to write a little program that uses the Net::HTTP library to
fetch a text file.  The text file has lines broken up by newlines, and I
thought I could use the .to_a method to convert a variable into an array,
but when I do it it puts the entire text file into the first marker on the
array, and the rest are nil.

Here's the program.  I know I'm missing something grotesquely obvious, and
thanks in advance for beating me with the clue stick.

What I expected was for test to return what it returns, but test2[0] to
return "This" and test2[1] to return "is".  Test2[0] returns identical
results to test.

require 'net/http'
require 'uri'

filename = 'test.txt'

def testget(filename)
url = URI.parse('http://vineland.lib.muohio.edu/' + filename  )
req = Net::HTTP::Get.new(url.path)
res = Net::HTTP.start(url.host, url.port) {|http| http.request(req) }
end

test = testget(filename)
test2 = test.to_a
puts test
puts test2[0]
puts test2[1]
