Router firewall and validating identity
For NGINX Plus, we also show how the cache can be distributed across a cluster of NGINX Plus instances, by updating the key‑value store with the Java Script module, as introduced in .
Except where noted, the information in this blog applies to both NGINX Open Source and NGINX Plus.
The Java Script code then parses the response (line 5) and sends the appropriate status code back to the so that errors can be distinguished from invalid tokens.
Note: This code is provided as a proof of concept only, and is not production quality.
The NGINX Plus module performs offline JWT validation.
Typically, a JWT also includes an expiry date which can also be checked.The response from the Id P is inspected, and authentication is deemed successful when the .This solution is a compact and efficient way of performing OAuth 2.0 token introspection with NGINX, and can easily be adapted for other authentication APIs. The single biggest challenge with token introspection in general is that it adds latency to each and every HTTP request.Note that the access token sent in the introspection request is a component of the body defined in line 14.Here function makes an HTTP subrequest (line 2) to another location (/oauth2_send_request) which is defined in the configuration snippet below.
