async http request

[Bob Aman]

I'm currently working on a ruby on rails page that needs to query a
web service, retrieve a few rss feeds and do a whole bunch of SQL
queries. Right now, my code is doing all of this somewhat
inefficiently. Ideally, I'd like to be able to do the http requests
on the page asynchronously if possible. However, I have yet to find
any example code or documentation that shows how to do this. I saw
the http-access2 library, though that seemed quite complicated
compared to the open-uri method I'm using now. Any suggestions about
how best to go about this? In the end, I really just need to have it
work, and have it be fast.

This is on the server, correct?

Can you use Ruby threads for each of the various requests?

Bob-

How about this?

def request_urls(urls = [])
reqs = []
urls.each do |url|
reqs.push Thread.new { open(url) }
end

reqs.collect { |req| req.value }
end

responses = request_urls [ 'http://www.blahr.com/', 'http://www.news.com/' ]

Just checked, and this does seem to work. Thanks!
