Under normal circumstances, when using proxy_cache_bypass nginx will fetch a fresh copy from upstream, and overwrite the cached response with the new one.

But if the URL changes from a cacheable to a non-cacheable response (for example to a 4xx response with Cache-Control: no-cache), then using proxy_cache_bypass will indeed serve a fresh copy from upstream, but it will leave the old copy in the c ...

I'm trying to set up a VPS with a single IP address to run my static homepage and some additional services such as NextCloud. I already have a domain that points to the VPS's IP address. Reading through a number of tutorials on self-hosting, a common solution for this type of scenario is to set up a reverse proxy that forwards to different subdomains, e.g. nextcloud.mydomain.com. However, here's my ques ...

This is my nginx.conf

I set up nginx as a reverse proxy for two proxied servers. Each of them (proxy and proxied servers) is running as a container in a docker environment. Proxied server appalpha is simply an nginx:alpine serving a static webpage (just for demo and testing purposes). All works fine here because things are simple. The other proxied server's image is kanboard/kanboard. When I try to access this service through ...

I'm trying to setup the following:

• docker container with nginx on localhost as a reverse-proxy for Wordpress, listening on localhost:80. It is also used as a reverse-proxy for other microservices.
• docker-compose container(s) with Wordpress+Apache, listening on localhost:4261. The docker-compose.yaml was taken from the official example. The 'ports' directive was changed from "8000:80" --> "4261:80".

nginx reverse proxy doesn't work with POST request returning 404 error

and when try the URL with a POST request

I currently use SNIProxy (it's the simplest I've seen so far to set up virtual hosts). However, I can only set SSL certificates separately per virtual host with each service's configuration (each one is on a separate port), which can quickly become a problem, and not for the server as a whole, so I only need a certificate for the reverse proxy. So, is there a way to do it? Alternatively, is there a reve ...

I'm using this configuration to nginx proxy reverso

can you guys help me ?

I have a setup where I have multiple service running with docker compose and one Nginx (nginx:1.19-alpine), which acts as a reverse proxy for all services and serves some static files.

One service is an Influxdb container (influxdb:2.1.0-alpine) which provides a UI for webbrowsers.
I want to reverse proxy to this container, but I get problems with the static files of this container.

We are using ProxyPass and ProxyPassReverse to redirect traffic to our application. how can I setup a maintenance page when we are performing deployments.

I am running a service on a docker container. The service is exposed on a given port (eg. 12345).

On top of it I added a nginx reverse proxy to get extra functionality like HTTPS and HTTP/2.

nginx configuration is the following:

http {
    sendfile        on;

    gzip  on;

I have a case where I need to proxy pass a domain (domain1.com) to a different domain (domain2.com) hosted on a shared ip address (192.168.168.168), but domain2.com DNS is pointed other than the shared ip address, so domain2.com cannot be used as the proxy pass, only the shared ip address.

Since the shared ip address has multiple hostnames, is there a domain or hostname configuration option that  ...

Nginx (19.x) is used as reverse proxy for nodejs backend server (ubuntu). Here is the nginx conf file for reverse proxy:

server {

I recently uninstalled apache2 for Nginx I'm trying to listen on 88, 808 and 888 for my sites and redirect different subdomains for each (and another domain to another server). the problem is that Nginx is giving bad gateway for all proxied requests and timeout for the direct ip access.

it's very hard to find something on google - you get too many results from nginx and proxy alone.

I'm trying to secure containers on my homelab.

The main goal is:

• isolating nginxA and nginxB from localhost, making them exclusively accessible via traefik

First, I apologize if this isn't the right forum as this is somewhat of a networking question.

To give a brief explanation of what I want to achieve is basically have the services or apps provided by Synology be accessible via a simple URL without port numbers. I have a dedicated IP address, so I don't have to worry about setting up DDNS.

I'm trying to set up a reverse proxy to my api server but getting a 404 error page.

Context: Whilst setting up a react.js application and trying to find a solution to the CORS problem, I've decided to use reverse proxy (proxy pass) with nginx to invoke the api server internally and trick the browser to think the api is on the same domain.
