I have a php site with location /app served by Java app server on same  
server port 9001

What is in /app/ should become / (root) for Java app server

I have this in config:

server {  
…  
index index.html index.htm index.php;

location /app {

```
            proxy_pass http://localhost:9001;
            proxy_next_upstream error timeout invalid_header

```

http\_500 http\_502 http\_503;

```
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For

```

$proxy\_add\_x\_forwarded\_for;

```
            proxy_set_header X-Forwarded-Proto https;

            proxy_redirect off;
  }

 location / {
          # First attempt to serve request as file, then
            # as directory, then fall back to index.html
            try_files $uri $uri/ /index.php?$args;
    }

```

location ~ index.php$ {

```
    try_files $uri =404;

    include fastcgi_params;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME

```

$document\_root$fastcgi\_script\_name;  
fastcgi\_pass 127.0.0.1:9000;  
}  
}

with this configuration, Java server receives requests like “GET /app/”  
while it should receive “GET /”

If I add trailing slash to proxy\_pass:

proxy\_pass [http://localhost:9001/](http://localhost:9001/);

Then java server receives “GET //” and unable to serve that either.

Do I need to involve rewrite here ? And how? or extra trailing slash is  
caused by other rewrite rules somehow?

Thank you!

Just a side note, you don’t need explicit set $args here.

```
try_files $uri $uri/ /index.php;

```

Documentation already has answers to your questions:

E.g., in your case:

```
location /app/ {
    ...
    proxy_pass http://localhost:9001/;
}

```

Thanks Valentin.

I get it now! I had  
location /app {

and it should be  
location /app/ {

with trailing slash. Weird that it’s sensitive for that slash there.

Thanks.

Trivia: “location /app { … }” will match url "  
[http://domain.com/appwhatever](http://domain.com/appwhatever)"
