Description
Hi, i'm an nginx module developer.
While i was working on a project i noticed something strange: the PREACCESS_PHASE it's being called two times when a request hits the root ("/") URI.
I also tried to quickly develope a simple module for testing purposes
Here is the code:
https://pastebin.com/7ew4s9qW
This module just log "NEONGINXTEST" every time that the PREACCESS_PHASE it's called.
Doing just a simple curl request on the root URI, it logs "NEONGINXTEST" two times, instead of one time.
In all the other locations it logs the "NEONGINXTEST" only one time.
It's this normal?
Thanks you in advance.

Yes, this is normal. Consider reading How nginx processes a request to better understand what's going on.

Replying to mdounin:
Yes, this is normal. Consider reading How nginx processes a request to better understand what's going on.
But considering that "limit_req" module (for example) is using the PREACCESS PHASE to lookup the visitor's IP into the binary tree, it's not a lose of performance?
