Ask HN: Does anyone have experience scraping dynamic content?

PhantomJS/CasperJS is what I've used for my current scraping projects. They're headless browsers and imitate a browser session. Just specify a fake user agent like Mozilla, and you're good to go.

You MAY be able to do this with Selenium, although I've never used Selenium to scrape streaming requests. It's going to depend quite a bit on how the page is structured.

I have used Selenium to scrape dynamic content before by waiting for new DOM elements to be populated by AJAX, so I know this sort of thing is possible in a way you couldn't do with wget.

yea, just look at the http headers, here's the call: http://www.nfl.com/liveupdate/scores/bigPlayVideos.json?rand...

HtmlUnit has very good support for javascript. http://htmlunit.sourceforge.net/
