Contrat

• Sinatra negotiates Accept header quality values within a provides route to assign the matching Content-Type and cascades to 404 on unaccepted types while evaluating separate routes in strict declaration order.
• assert provides with multiple formats selects the format with the highest client Accept quality factor and sets Content-Type
• assert provides defaults to the first format in the list when the client Accept header is absent or wildcard */*
• assert provides rejects unmatched Accept headers with 404 and X-Cascade: pass
• assert separate routes sharing a path evaluate in top-down declaration order rather than by client quality factor preference
• assert custom MIME types registered via mime_type integrate with provides and content_type
• assert content_type appends charset=utf-8 to text MIME types while leaving binary types without charset parameters
• assert attachment sets Content-Disposition and infers Content-Type from filename
• assert cache_control and expires format Cache-Control directives and HTTP-date Expires headers
• assert etag halts with 304 on matching GET If-None-Match, supports weak tags, and enforces 412 Precondition Failed on mutating requests
• assert last_modified halts with 304 on equal or newer If-Modified-Since timestamps
