根因分析

重写规则或try_files指令导致无限循环，因为重写后的URI反复匹配同一个location块。

English

A rewrite rule or try_files directive causes an infinite loop because the rewritten URI matches the same location block repeatedly.

官方文档

解决方案

  1. 在重写规则中添加break标志：rewrite ^/old/(.*)$ /new/$1 break;
  2. 为目标URI使用单独的location以避免递归：location /new/ { ... }
  3. 用try_files和命名location替换重写：try_files $uri @fallback; location @fallback { ... }

无效尝试

常见但无效的做法:

  1. 90% 失败

    Logging doesn't break the cycle; it only helps debug.

  2. 70% 失败

    This prevents external access but may still cycle internally if rewrite triggers same location.

  3. 95% 失败

    Timeouts don't affect rewrite loops; they are unrelated.
