Please help with proxy_pass and trailing slash!

[Roddick]

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/;

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:
http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass

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"
