During the last days I spent considerable amount of time solving issues with my location definitions.
Sometimes I could see attempts to open files in the error.log, sometimes not.

I know there is https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/ but wanted to ask if there is a list of best practice troubleshooting advice or even some tool or debugging switch that can help me find out which location gets used for a specific URL or URL pattern_______________________________________________
