When implementing robots.txt for Bingbot, what directive definitively prevents a subdirectory named 'private' within your domain from being crawled, regardless of other rules?

The 'Disallow: /private/' directive in robots.txt specifically prevents Bingbot from crawling any files or subdirectories within the '/private/' directory, regardless of other rules within the file. The 'Disallow' directive tells search engine crawlers which parts of a website they should not access. The forward slash '/' before 'private' indicates that it is a subdirectory at the root level of the domain. Because the directive is specific to the '/private/' directory, even if other rules exist that might allow access to certain files, the 'Disallow' rule will always take precedence for this particular directory and its contents. This ensures that Bingbot will not crawl anything located within '/private/'. For example, if you had a rule allowing crawling of '.html' files, but also disallowed '/private/', any .html files within '/private/' would still be blocked from crawling.
