Is there an easy way to redirect [foo.com](http://foo.com) to [www.foo.com](http://www.foo.com) in nginx?  
Either that or if somebody knows a way to get restful authentication to  
store a cookie for either [www.foo.com](http://www.foo.com) or [foo.com](http://foo.com) that would be great.  
My current cookie is stored with this line:

cookies[:auth\_token] = { :value =\>  
self.current\_user.remember\_token,:expires =\>  
self.current\_user.remember\_token\_expires\_at }

I tried adding :domain =\> ‘.foo.com’ but that didn’t seem to work. I  
figure the nginx redirect would be the easiest thing…

Thanks.

I’m using something like the following and it seems to work OK:

```
server {
    server_name www.foo.com;
    rewrite ^/(.*) http://foo.com/$1 permanent;
}

```

Yeah for some reason that doesn’t work for me. After I do that and go  
to [foo.com](http://foo.com) it instead redirects me to one of the other vhosts on that  
server. Weird.

Ok, the “for some reason” I mentioned below turns out to be the order  
in which my vhosts were listed. The redirect always goes to the first  
vhost that was setup… probably a bug in nginx or perhaps a snafu in  
my config. Moving my [foo.com](http://foo.com) entry to the front of the line enabled  
your rewrite line to work.

Thanks,  
Vince

nginx defaults to the first vhost when it can’t find the host so it  
may well be your re-write isn’t working.

I hadn’t tried that, but I get this regardless of where I insert it:

Starting nginx: 2007/09/28 10:12:22 [emerg] 5696#0: unknown directive  
“RewriteEngine” in /etc/nginx/nginx.conf:21

I tried putting it both before sendfile on; and also inside my server  
block but with the same results.

This will be working only if host end with /, and you redirect from  
[www.foo.com](http://www.foo.com) to [foo.com](http://foo.com).

Try this example:

server {  
server\_name [foo.com](http://foo.com);  
rewrite ^(.\*)$ [http://www.foo.com$1](http://www.foo.com$1) permanent;  
}
