I developed a Nginx 3rd party dynamic module and did required configuration in nginx.conf. Able to run that module and see it doing processing. This module reads request request header, cookies etc., does some business logic execution and modify response header then send back response to client.
Problem -: "How to use nginx module when proxying connections to application servers"
I'm be using Nginx as proxy server and Tomcat or Node as application server and my application hosted on app server. I'm able to route the request through both web & app server and get response back but module isn't getting invoked. Not sure how to link/configure it so that my able to intercept request and modify response header as per need.
Flow -: Browser <-> Web Server (module sits here) <-> Application Server
Has anybody explored this part? If yes then please help.

I am investigating some background Http requests made by a third party module. I want to route all such requests (I don't know where they are located) through a proxy (Fiddler) configured at the PC level so that I can inspect the payload and responses.
Is there a way to transparently make all network requests in a Node app follow the PC's proxy settings?
A web server responds to an HTTP request and sends the client a set of HTML, CSS, and JS files.
After we build a website or a web application, we usually have to host it on a well-known web server like IIS or Apache to make it accessible all around the world (on the internet).
Can't we just make our own web server so that it can responds to all incoming HTTP requests that the client sends to our computer without having to use IIS?
As wazz and Lex says, you could build your own server to listen the special port and handle the request based on your requirement, but it contains performance and security issue.
If you still want to build it by yourself. I suggest you could refer to some existing server like KestrelHttpServer.
I have an NodeJS API using Express Framework.
I use Nginx for Load Balancing betwween my NodeJS instances. I use PM2 to spawn NodeJS Instances.
I identified in the log that Ngnix makes some "dummy/internal" requests, probably to identify if the instance is on (heartbeat requests could be the appropriate name for this requests).
My question is: Which is the right method to identifiy these "dummy/internal" requests on my API?
I'm fairly certain that nginx only uses passive health checks for upstream servers. In other words – because all HTTP requests are assumed to result in a response, nginx says "If I send this server a bunch of requests and don't get responses for them, I'll consider the server to be unhealthy".
Can you share some access logs of the requests you're seeing?
As far as I know, nginx does not send any requests to upstream servers that are not ultimately initiated by a client.
it's a little bit weird, but a 3rd party application has an embedded IE with a configureable static URL. This IE calls my webserver (nodeJS). The application has no parameter for the url, so I have a simple nodeJS app which starts with the login of the user and connect to the webserver (websocket). This app is able to see the dynamic parameter of the 3rd party app by looking in the user registry. Both together I would the information to bring the right data to the embedded IE. But how can the webserver relate the IE request to the websocket connection of the "registry app". The websocket app knows the NT username and many more, but the IE only sends a simple http request.
If it wasn't a terminal-services, I would the IE run over the a local webserver, which would forwarding the request plus the registry data to the real webserver (like a proxy). But it's a terminal-services, so there is the port blocking problem. Or is there a way to bind a server to a kind of "virtual per user ip" on the same port?

I'm running a node application on heroku and I would like to find the full request URL through which my application is being requested. In particular, I want to know if it has been accessed through HTTP or HTTPS, so that I can redirect clients connecting through HTTP to use the same URL but with HTTPS instead.
Since the application is running under proxies, etc., the protocol and host portions of the requests I can read are the ones where node is running, as forwarded by Heroku infrastructure.
Hints appreciated!
BTW, my app uses requestjs, in case that is relevant
