Subject: Net::HTTP and handling 302 Redirect

Greetings all. Ruby n00b here.

I'm trying to use Ruby against ning.com's REST api. My code is close
to working, but I don't understand the redirect example provided in
the Net::HTTP code. I'm hoping that someone can point me in the right
direction.

--- Here's my code ---

#create XML message
msg = <<eof
  blah blah
eof
doc = REXML::Document.new( msg )

url = URI.parse("https://mySite.ning.com/xn/atom/1.0/content")

@req = Net::HTTP.new(url.host)
@req.use_ssl = false     #not using ssl
@req.set_debug_output $stderr
@req.start() do |req|
    postReq = Net::HTTP::Post.new(url.path)
    postReq.basic_auth('user', 'password')
    postReq['Content-Type']=req.head(url.path)
    postReq.body = doc
    print postReq

    response = req.post(url.path, postReq)
end

This results in the following at the command line when I run:

<- "HEAD /xn/atom/1.0/content HTTP/1.1\r\nAccept: */*\r\nHost:
mySite.ning.com\r\n\r\n"

Anyone have any suggestions?  So clueless here. :-)
