keyword-onlyoptionalstrategy: Literal['all', 'same-domain', 'same-hostname', 'same-origin']
Enqueue strategy to be used for determining which links to extract and enqueue.
Options: all: Enqueue every link encountered, regardless of the target domain. Use this option to ensure that all links, including those leading to external websites, are followed. same-domain: Enqueue links that share the same domain name as the current page, including any subdomains. This strategy is ideal for crawling within the same top-level domain while still allowing for subdomain exploration. same-hostname: Enqueue links only if they match the exact hostname of the current page. This is the default behavior and restricts the crawl to the current hostname, excluding subdomains. same-origin: Enqueue links that share the same origin as the current page. The origin is defined by the combination of protocol, domain, and port, ensuring a strict scope for the crawl.

List of regular expressions or globs that URLs must match to be enqueued.
keyword-onlyoptionalexclude: list[re.Pattern | Glob]
List of regular expressions or globs that URLs must not match to be enqueued.
