Also didn’t realise I could use the actual code instead of a constant.

Is it possible to issue any status code or are we limited to those in  
ngx\_http\_lua\_consts.c?

Cheers.

Sure. Just use ngx.exit(501) for it.

The constants defined there are just for improving Lua code readability.

You can use any status code. See

```
http://wiki.nginx.org/HttpLuaModule#ngx.exit

```

BTW, I’ve already added constant ngx.HTTP\_METHOD\_NOT\_IMPLEMENTED to  
ngx\_lua v0.3.1rc12:
