 * This is a project designed to get around sites using Cloudflare's "I'm under attack" mode.
 * Using the PhantomJS headless browser, it queries a site given to it as the second parameter,
 *  waits six seconds and returns the cookies required to continue using this site.  With this, 
 *  it is possible to automate scrapers or spiders that would otherwise be thwarted by Cloudflare's 
 *  anti-bot protection.
 * 
 * To run this: phantomjs cloudflare-challenge.js http://www.example.org/

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
