in intranets and the internet can now choose to appear as Googlebot. This is an essential necessity to be able to compete in the field of commercial search appliances, since most web pages are these days optimized only for Google and no other search platform any more. All commercial search engine providers have a built-in fake-Google User Agent to be able to get the same search index as Google can do. Without the resistance against obeying to robots.txt in this case, no competition is possible any more. YaCy will always obey the robots.txt when it is used for crawling the web in a peer-to-peer network, but to establish a Search Appliance (like a Google Search Appliance, GSA) it is necessary to be able to behave exactly like a Google crawler. With this change, you will be able to switch the user agent when portal or intranet mode is selected on per-crawl-start basis. Every crawl start can have a different user agent.
