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?
Have you looked at Net:HTTP ?
Ruby Net::HTTP class would support such requests
there are some other classes/gems that are worth looking at:
net/https for secure connections
especially hpricot is very handy if you have to process the returned
html or xml
