Spider traps

Bounded spider-trap and honeytrap fixtures covering path depth, incrementing parameters, calendar walks, session-id URLs, faceted explosion, unique-token chains, hidden links, and a 10 MB body.

Fixtures that look like unbounded crawl spaces but are not: every trap family is a parameterised route with a hard server-enforced cap, a deterministic structure, and a visible stop page. A crawler that ignores the bound always reaches a terminal 200 page carrying a stop marker — there is no genuinely infinite generation anywhere in this group.

Families:

• Path depth: a 25-level chain where each level links only to the next; level 25 ends the chain.
• Query increment: an incrementing page parameter series capped at 50.
• Calendar: prev/next month walking over a fixed 2025-01 to 2028-12 range (48 months, never today-relative).
• Session id: a sid parameter that looks session-generated but is a deterministic hash of each target path; depth capped at 3 (40 URLs).
• Faceted navigation: a 5x5 hub of 25 near-duplicate combinations, and a four-dimension hub capped at exactly 500 of 625 possible combinations.
• Unique-token URLs: a chain of unique-looking token segments, each the deterministic hash of its parent path, capped at 5 hops.
• Hidden and noscript links: display:none, visibility:hidden, white-on-white, and noscript-only anchors, each pointing at a target page reachable only through the concealed link.
• Oversized response: a streamed HTML body of exactly 10,485,760 bytes with start and end markers and a four-request concurrency cap.

The high-volume 10,000-link page belongs to the links group as links-10000-unique and is deliberately not duplicated here; deeply nested and adversarially malformed HTML are parser-stress fixtures owned by the exotic advanced group.

Every trap entry point is risky, direct-entry only, and appears in no sitemap; trap waypoints, stop pages, and hidden-link targets are never emitted anywhere except the canonical manifest. The four hidden-link entry pages are moderate and safe to crawl broadly.

Fixtures in this category

• Hidden link — display:none — hidden-display-none-link (moderate)
• Hidden link — visibility:hidden — hidden-visibility-hidden-link (moderate)
• Hidden link — white on white — hidden-white-on-white-link (moderate)
• Hidden link — noscript only — noscript-only-link (moderate)
