nginx在用户使用ie的使用重定向到/nginx-MSIE目录下

[root@web01 ]# cat /app/server/nginx/conf/rewrite/default.conf
#rewrite ^/index\.html /index.php last;
#if (!-e $request_filename) rewrite ^/(.*)$ index.php last;
#if (!-e $request_filename) {rewrite ^/(.*)$ /index.php last;}
#if (!-e $request_filename) {return 404;}
if ($http_user_agent ~ Firefox) {rewrite ^(.*)?$ /nginx-Firefox/$ break;}
if ($http_user_agent ~ MSIE) {rewrite ^(.*)$ /nginx-MSIE/$ break;}
#rewrite ^/(\d+)/(.+)/ /$/$ last;
