Redirect rule reference

Fields of a redirect rule, their defaults, how they are normalized and the limits that apply.

On this page

Redirect rules are the redirects list of a zone's edge settings. A PATCH replaces the whole list. Unknown fields are rejected.

FieldDefaultRules
host—Required. A full name of the zone (the zone or below it), no wildcard. Stored in lower case without a trailing dot.
path_prefix/Starts with /; no ?, #, spaces or control characters; at most 1024 characters. Stored in canonical form: non-ASCII and reserved characters as upper-case %XX (/año and /a%c3%b1o are both stored as /a%C3%B1o; %2F counts as /). Unique per host.
target—Required. Absolute http:// or https:// URL, at most 2048 characters, without user:password@, fragment or spaces; may carry a query. The scheme is stored in lower case and non-ASCII bytes of path and query as %XX; write the host in ASCII (punycode for international names).
preserve_pathtrueAppend the rest of the path after the prefix.
preserve_querytrueAppend the request's query string.
status301301, 302, 307 or 308.

Limits

  • At most 50 rules per zone.
  • A rule can't redirect to its own host on a path it captures.
  • Redirect rules can't be set per name under hosts: each rule already names its host.

Errors

Invalid rules are rejected with 422 and a message that names the rule, for example redirects[0].host: "shop.example.org" is not a name of the zone example.com.
