> the current implementation of the HttpClient will not cache any requests to the robots.txt file. While using the CrawlingWorker this will result in 2 requests to the robots.txt (HEAD + GET) per crawled URL. So when crawling 3 URLs the target server would get 6 requests for the robots.txt.
> unfortunately the contentLoader is made final in HttpProtocol, so there is no possibility to replace it with a caching Protocol like that one you'll find in the attachment.
