"Moved Temporarily"?

Ilán Terrell

9/8/2003 11:35:00 PM

When trying to run the following code from "Programming Ruby" I get an
error message stating
Fetching: www.rubycentral.com
Fetching: www.awl.com
Fetching: www.pragmaticprogrammer.com
Got www.rubycentral.com: OK
/usr/lib/ruby/1.6/net/protocol.rb:221:in `error!': 302 "Moved
Temporarily" (Net::ProtoRetriableError)
from /Users/ilanterrell/Documents/ RubyScripts/threads.rb:20:in
`join'
from /Users/ilanterrell/Documents/ RubyScripts/threads.rb:20
from /Users/ilanterrell/Documents/ RubyScripts/threads.rb:20:in
`each'
from /Users/ilanterrell/Documents/ RubyScripts/threads.rb:20
I am pretty new to ruby and I don't have the slightest clue what "Moved
Temporarily" means. I have tried this on multiple platforms and get the
same error. Any ideas?

#!/usr/bin/ruby
require 'net/http'

pages = %w( www.rubycentral.com
www.awl.com
www.pragmaticprogrammer.com
)
threads = []

for page in pages
threads << Thread.new(page) { |myPage|

h = Net::HTTP.new(myPage, 80)
puts "Fetching: #{myPage}"
resp, data = h.get('/', nil )
puts "Got #{myPage}: #{resp.message}"
}
end

threads.each { |aThread| aThread.join }

???? ???

That''s an HTTP error code; I don''t believe it has anything to do with the Ruby code, other than that it''s passing on what the web server sent it.

I would imagine what the error means is that the web page has been moved to some other location.

Cheers,

Exactly right.

It does. The headers that are returned in that request should include
one labelled "Location:", which is the new URL.

"302" means that the old URL should still be used, and is /not/
obsolete. If it were "301", you should change the URL and use the new
one, always.

Yes, but if you run it using ruby 1.8.0 it does not throw any error,
just displays the HTTP error (along with some warnings).
On Windows XP Pro (using /\ndy''s one-click installer)
