I have nginx proxying to an app server, with the following configuration:
location /app/ {
# send to app server without the /app qualifier
rewrite /app/(.*)$ /$1 break;
proxy_set_header Host $http_host;
proxy_pass http://localhost:9001;
proxy_redirect http://localhost:9001 http://localhost:9000;
}
Any request for /app goes to :9001, whereas the default site is hosted on :9000.
GET requests work fine. But whenever I submit a POST request to /app/any/post/url it results in a 404 error. Hitting the url directly in the browser via GET /app/any/post/url hits the app server as expected.
I found online other people with similar problems and added
proxy_set_header Host $http_host;
but this hasn't resolved my issue.
There are no errors logged, and the access logs are as follows:
# For http://localhost:9000 (no proxying)

Any insights are appreciated.
Thanks.

location /app/ {
# rewrite here sends to app server without the /app qualifier

My bad, the problem wasn't nginx, it was my app server. I was using a routing module that required me to explicitly specify the request method if not a get, and so that's why it was throwing a 404 error on post, but not when hitting the browser url directly.
