Guys, you don't need a freaking browser to load a single page.

This is a simplified example. Normally, you would introduce a proper HTTP client (external gem or wrapper around net/http), request retries, response validations, user agent injection (this website doesn't care really), cookie injection (technically, they use JSESSIONID but it does nothing and can be skipped) and other standard stuff.

@ocvit this is absolutely better than using a browser. The initial consideration of using a browser stemmed from not know how Vaadim pages work, but since you have gotten it to work with net/http it is of course so much better. Thank you for your contribution!
