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 processes for issuing, presenting, and validating an OAuth 2.0 authentication flow often rely on several related standards.
Authentication is required for the Id P to accept token introspection requests from this NGINX instance. With this configuration in place, when NGINX receives a request, it passes it to the Java Script module, which makes a token introspection request against the Id P.This can become a significant issue when the Id P in question is a hosted solution or cloud provider.NGINX and NGINX Plus can offer optimizations to this drawback by caching the introspection responses.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.It is supported by many of the leading Id P vendors and cloud providers.
