html-metada(preq) being blocked by DDOS arrest #26

Hi guys, thank you for this wonderful module.

I just wanna ask help regarding this ddos protection issue. It seems that this module can't get through some site with ddos protection(DDOS arrest). Like this gulfnews website: http://gulfnews.com/news/uae/health/health-authority-launches-campaign-for-safe-disposal-of-expired-medicines-1.1637255

Is there any way around this?

Thanks Mark

We don't use the request bit of this library ourselves, only the methods once the cheerio object has been loaded, but we don't seem to have a problem with that site in citoid (https://github.com/wikimedia/citoid/blob/master/lib/Scraper.js). It might be because we use cookies in citoid?

Instead of the url as the first argument, you can also pass an options object like with the request library: https://github.com/request/request#requestoptions-callback

So in this options object you can put the url, a cookie jar, a user-agent string, etc. Some websites might flag block if you make the request without the user-agent string, that could also be the issue.

Hi mvolz!

Thank you for the quick response. The user-agent header did the trick! Thank you so much!
