Hello,

I set up a reverse proxy for a client with Nginx.

I still have a problem when I click on a link but the name of the  
directory doesn’t end with a slash.

The proxy address is [http://proxy.com](http://proxy.com) and all requests are returned to  
[http://mydomain.com](http://mydomain.com)

Example: [Proxy](http://proxy.com/test/) and reference works well inside  
[http://mydomain.com](http://mydomain.com) but remains on [Proxy](http://proxy.com/test/)

If I remove the slash of the end I don’t have [Proxy](http://proxy.com/test) in  
the address bar but [http://mydomain.com/test/](http://mydomain.com/test/) (with slash at the end  
because the other web server adds).

In the http headers I see a 301 but it is not handled by nginx visibly:

[http://proxy.com/test](http://proxy.com/test)

GET /test HTTP/1.1

Host: [proxy.com](http://proxy.com)  
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:2.0.1) Gecko/20100101  
Firefox/4.0.1

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,_/_;q=0.8

Accept-Language: en-us,en;q=0.5

Accept-Encoding: gzip, deflate

Accept-Charset: ISO-8859-1,utf-8;q=0.7,\*;q=0.7

Keep-Alive: 115

Connection: keep-alive

Cookie: language1=en; language2=en

HTTP/1.1 301 Moved Permanently

Server: nginx/0.7.67

Date: Wed, 18 May 2011 07:15:57 GMT

Content-Type: text/html; charset=iso-8859-1

Transfer-Encoding: chunked

Connection: keep-alive

Location: [http://mydomain.com/test/](http://mydomain.com/test/)

Age: 108

I thought to rewrite the rules but it might cause trouble.

If anyone has an idea on the subject, I’m interested.

Thank you

events {  
worker\_connections 1024;  
# multi\_accept on;  
}

http {  
include /etc/nginx/mime.types;

```
access_log /var/log/nginx/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;

gzip on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

```

}

my vhost :  
server {  
listen [::]:80;

```
   server_name proxy.com *.proxy.com;

   access_log /var/log/nginx/proxy_.access.log;

   error_page 404 = /404.htm;

   location /404.htm {
     root /var/www;
   }

   location / {
       proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

if ($host ~* ^proxy\.com$) {
   proxy_pass http://mydomain.com;
}

if ($host ~* ^www\.proxy\.com$) {
   proxy_pass http://www.mydomain.com;
}

if ($host ~* ^subdomain\.proxy\.com$) {
   proxy_pass http://subdomain.mydomain.com;
}

proxy_redirect http://proxy.com/test http://proxy.com/test/;

```

}  
}

proxy\_redirect [http://mydomain.com](http://mydomain.com) [http://proxy.com](http://proxy.com);  
proxy\_redirect [http://www.mydomain.com](http://www.mydomain.com) [http://www.proxy.com](http://www.proxy.com);  
proxy\_redirect [http://subdomain.mydomain.com](http://subdomain.mydomain.com) [http://subdomain.proxy.com](http://subdomain.proxy.com);

BTW, your configuraiton is wrong mix of levels: you should not use  
virtual host name on location level in “if ($host ~”. This leads  
to cumbersome and unmaintainable configurations.  
Instead you should define 3 separate servers:

server {  
server\_name [proxy.com](http://proxy.com);  
location / {  
proxy\_pass [http://mydomain.com](http://mydomain.com);  
}  
…  
}

server {  
server\_name [www.proxy.com](http://www.proxy.com);  
location / {  
proxy\_pass [http://www.mydomain.com](http://www.mydomain.com);  
}  
…  
}

server {  
server\_name [subdomain.proxy.com](http://subdomain.proxy.com);  
location / {  
proxy\_pass [http://subdomain.mydomain.com](http://subdomain.mydomain.com);  
}  
…  
}
