        前提true.html文件不存在    
        配置
                 location ~ /error.html {
        rewrite ^/(.*) /true.html break;
        }

        location ~ /true.html {
          if ( !-e $request_filename ){
          return 508;

使用break，不在匹配server{}中的location，由于不存在文件，直接返回404.

    配置
     location ~ /error.html {
        rewrite ^/(.*) /true.html last;
        }

        location ~ /true.html {
          if ( !-e $request_filename ){
          return 508;
          }
        }

使用last，重新匹配server{}中的location，返回匹配到location ~ /true.html 中的508.
