Can ruby support send http request or call other programs written in like c or c# or Java?

hello, everyone,
I am developping a website using Ruby on Rails which need to go to
another website to get some information to update my own database.
Does ruby have similar function support like in c#:WebRequest.Create
And how I call other programs in Rails?

Many thanks,


Could you please repost the question to rubyonrails-talk or even ruby-
talk please?
