sinatra

I have a Sinatra app with a long running process (a web scraper). I'd like the app flush the results of the crawler's progress as the crawler is running instead of at the end.

I've considered forking the request and doing something fancy with ajax but this is a really basic one-pager app that really just needs to output a log to a browser as it's happening. Any suggestions?
