Module ngx_http_internal_redirect_module

Example Configuration

The ngx_http_internal_redirect_module module (1.23.4) allows making an internal redirect. In contrast to rewriting URIs, the redirection is made after checking request and connection processing limits, and access limits.

This module is available as part of our commercial subscription.

Example Configuration

limit_req_zone $jwt_claim_sub zone=jwt_sub:10m rate=1r/s;

server {
    location / {
        auth_jwt          "realm";
        auth_jwt_key_file key.jwk;

        internal_redirect @rate_limited;

    location @rate_limited {

        limit_req  zone=jwt_sub burst=10;
        proxy_pass http://backend;

The example implements per-user rate limiting. Implementation without internal_redirect is vulnerable to DoS attacks by unsigned JWTs, as normally the limit_req check is performed before auth_jwt check. Using internal_redirect allows reordering these checks.


Syntax: internal_redirect uri;
Context: server, location

Sets the URI for internal redirection of the request. It is also possible to use a named location instead of the URI. The uri value can contain variables. If the uri value is empty, then the redirect will not be made.
