Ce que l'on suppose souvent

Evaluating ReplaceKnown on an unset http.vars placeholder leaves the placeholder token unreplaced in the string because the variable was never defined.

L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.

Contrat

• The caddyhttp replacer recognizes all {http.vars.*} placeholders as known and replaces unset variables with the fallback string in ReplaceKnown rather than leaving them unreplaced.
• Context variables set via caddyhttp.SetVar are dynamically resolved by {http.vars.<name>} placeholders in the replacer.
• Setting a variable to nil via caddyhttp.SetVar deletes it from the request context variable map.
• The replacer resolves standard HTTP request properties such as method, path, query parameters, and headers alongside custom context variables.
• VarsMatcher evaluates placeholders in rule values against stored context variables without expanding placeholder syntax inside the stored values.
