Redirect chain
Two or more redirects before a final response.
What Redirect chain means
Each hop adds failure and latency opportunities, while clients impose different maximums.
How CrawlCheck measures Redirect chain
One finding code measures it. Its share of all scans is computed from the live corpus when this page is served, not typed into it.
| Finding code | Share of scans | Guide |
|---|---|---|
REDIRECT_CHAIN | 2.9% | dataset |
Every code, its rule and its current rate: the dataset page. Scan a site to see which apply to it.
Where Redirect chain comes up on this site
- How to audit an XML sitemap: status, content type, canonical URLs and stale entriesVerify the actual response, then tell it apart from a wall Fetch the headers and the body separately and read both: curl -sS -D /tmp/sitemap.headers -o /tmp/sitemap.xml https://example.com/sitemap.xml cat /tmp/sitemap.headers head -c 500 /tmp/sitemap.xml…
- HTTP status codes for crawlers: what a 200 can hide, when a 403 is not a block, and the one control that tells them apartFollow the homepage redirect chain with the hop statuses printed and note the final host.
- Canonical URL audit: one page, one address, and the three ways a site publishes it twiceThe redirect chain's final host tells you where the entity lives now; the canonical tags on the remaining pages tell you whether the site knows.
- HSTS audit: missing header, preload ineligible, removedStart with a short max-age such as 300 seconds while you confirm every subdomain and every redirect chain works over HTTPS, then raise it.
