499 status code - what is it and how to avoid it?

Response status code 499 is a rare status code which means that the server has unexpectedly closed the connection. In web scraping, this most likely means that the server has identified that the client is a web scraper and decided to stop serving content. Repeated 499 status codes can likely lead to a complete scraper block, so these errors should be addressed ASAP.
