linux – Nginx fastcgi cache in a block of different location

I'm trying to cache a different location with a different cache key box, but that does not work. The cache only works for the root location "https://serverfault.com/".

If I disable the cache for the location "https://serverfault.com/", it still does not work for another location.

Block Http:

fastcgi_cache_path /webcache/nginx levels=1:2 keys_zone=microcache:100m max_size=1000m inactive=45m use_temp_path=off;
fastcgi_cache_path /webcache/extreme levels=1:2 keys_zone=extreme:100m max_size=10400m inactive=99999m use_temp_path=off;
fastcgi_cache_key "$scheme$request_method$host$request_uri";

Server block:

location ~* "^/(20(0-1)(0-8)/)" {              
   try_files $uri $uri/ /index.php?$args;
    location ~ .php$ {
