30/307混合中的NGINX缓存无限循环

我步履蹒跚，这里确实需要一些帮助：

我有一个NGINX反向代理，它从上游CMS服务器提供内容。服务器配置为：

server {
listen 443 ssl;
server_name example.com www.example.com;
ssl_certificate /etc/nginx/ssl/example.com/fullchain.pem;
ssl_certificate_key /etc/nginx/ssl/example.com/privkey.pem;
ssl_trusted_certificate /etc/nginx/ssl/example.com/fullchain.pem;
add_header Content-security-policy upgrade-insecure-requests;
location / {
proxy_pass http://10.0.0.1;
proxy_redirect http:// https://;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}


请求index.php上游发出几个重定向（302和307）-没问题：

2019-12-28T11:28:15.269832284Z 1.2.3.4 - - [28/Dec/2019:11:28:15 +0000] "GET / HTTP/1.1" 302 145 "-" "Mozilla/5.0" "-"
2019-12-28T11:28:15.494911686Z 1.2.3.4 - - [28/Dec/2019:11:28:15 +0000] "GET / HTTP/1.1" 302 0 "-" "Mozilla/5.0" "-"
2019-12-28T11:28:15.698820671Z 1.2.3.4 - - [28/Dec/2019:11:28:15 +0000] "GET / HTTP/1.1" 307 0 "-" "Mozilla/5.0" "-"
2019-12-28T11:28:15.765285132Z 1.2.3.4 - - [28/Dec/2019:11:28:15 +0000] "GET /frontpage/ HTTP/1.1" 200 5379 "-" "Mozilla/5.0" "-"


但是，如果我向NGINX添加缓存功能，它将在302循环中陷入困境。我不知道为什么。这是配置：

nginx.conf中的缓存路径：

proxy_cache_path /var/nginx-proxy-cache levels=1:2 keys_zOne=my-cache:5m max_size=10g inactive=1y use_temp_path=off;


服务器配置：

server {
listen 443 ssl;
server_name example.com www.example.com;
ssl_certificate /etc/nginx/ssl/example.com/fullchain.pem;
ssl_certificate_key /etc/nginx/ssl/example.com/privkey.pem;
ssl_trusted_certificate /etc/nginx/ssl/example.com/fullchain.pem;
add_header Content-security-policy upgrade-insecure-requests;
# cache conf
proxy_cache my-cache;
proxy_cache_revalidate on;
proxy_cache_valid 5m;
proxy_cache_use_stale error timeout http_500 http_502 http_503 http_504;
proxy_cache_background_update on;
proxy_cache_lock on;
location / {
proxy_pass http://10.0.0.1;
proxy_redirect http:// https://;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}


再次请求index.php，它陷入一个无休止的循环，如下所示：

2019-12-28T11:13:26.193598796Z 1.2.3.4 - - [28/Dec/2019:11:13:26 +0000] "GET / HTTP/1.1" 302 145 "-" "Mozilla/5.0" "-"
