About Redirect Rules

• Return a location where the set of GET queries in the request exactly matches the set of queries in the redirect rule.
  • Order of GET queries is not considered.
• A redirect rule with no GET query specified becomes the default rule for that PATH.
  • If the GET query of the request does not match any of the redirect rules, the location of the default rule is returned.
  • If the default rule is not defined, the request does not match any of the redirect rules, status 404 returned.
• Redirect rules are domain-aware.
• If there are duplicate redirect rules, the first defined rule is returned.
• Extra GET queries are removed on redirect.
