http streaming in Rails 3.0.3 and thin server


In my site I am using 'thin' server and my environment is Rails 3.0.3 and Ruby 1.8.7. Certain pages in site take a long time to process and as I am hosting it on Heroku I get timeout errors frequently. I am planning to use http streaming in this setup. When I use curl on the command prompt I do see that transaction is chunked. Apart from this setup I haven't done any other change in the code to have http streaming. How do I confirm that page is actually loaded using http streaming and what changes do I need to do in code/setup to start http streaming?

I can't upgrade Rails/Ruby as the hosting on heroku is temporary and I may have to move to some other hosting service and I may not have the option to use higher versions of Rails/Ruby.

Thanks for any help in advance.
