In a cursory glance, this appears to be logic (token, redis, etc) that can be handled by Nginx+Lua. Is there any reason to do it this way vs the other?

The intent was to demonstrate how to write a module in C. This can be solved with Lua as well.

I was hoping for a performance related answer, but you are right. I might walk through this and see if one way is faster than the other. Thanks!

Using Lua is much easier. Performance is unlikely to be a bottleneck. Developing a module is a real pain and a last resort.
abedra
Using Lua is certainly easier. The C version will almost always be faster, and yes, performance in this scenario probably wouldn't be an issue between the two. The other reason for writing a module in C though is complete control over the execution and an easier time troubleshooting problems. Adding another language layer can present issues when things explode.

thanks for this. It came in just at the right time as I was looking into this.

I would also like to see this approach in Lua by comparison. I find the performance loss negligible compared to the ease of writing / debugging Lua.

I love how this tutorial starts by writing an automated integration test. More tutorials should do this. A fine job. Have a cookie.

Excellent tutorial, thank you for posting. All tutorials should be this complete.
