Hi.

I tried to rewrite all non-www url to www url, but when i tried to  
access the site, i got the infinite loop. following is my config

server {  
server\_name [www.example.com](http://www.example.com);

}  
location / {  
…

rewrite ^ http://example.com$request\_uri? permanent;  
proxy\_pass [http://example.com](http://example.com)

}

but if i change to redirect to the www url with locale(like, en, zh\_CN),  
it works fine. following is the config.

server {  
server\_name [www.example.com](http://www.example.com);  
}

location / {  
…

rewrite ^ [http://example.com/zh\_CN$request\_uri](http://example.com/zh_CN$request_uri)? permanent;

}

location ^~ /zh\_CN {  
…

proxy\_pass [http://example.com](http://example.com)  
}

any help is appreciated.

Thank You

Steve

do you want to proxy or rewrite? R

Also why do people like posting snippet of their config file? This one  
isn’t even a valid one with location block outside sever block.

hi

i would to have both rewrite and proxy. Rewrite is for redirecting  
non-www url to www urls, proxy\_pass is passing to my upstream block.

Thank You

server {  
server\_name [www.example.com](http://www.example.com);

location / {  
proxy\_pass [http://example.com](http://example.com);  
}

}

server {  
server\_name \*.example.com;

```
rewrite ^ http://www.example.com$request_uri? permanent;

```
