proxy-fix

This simple app simply spawns another HTTP server with PORT env injected with another number, then proxying it with a clean header request.

Built primarily for fixing phusion/passenger#2521 temporarily, then added more stuff for DOM Cloud purposes. HTTP and Websocket is supported.

Install

Download from releases or build it and place it to ~/.local/bin/proxfix.

PROXYFIX=proxy-fix-linux-$( [ "$(uname -m)" = "aarch64" ] && echo "arm64" || echo "amd64" )
wget https://github.com/domcloud/proxy-fix/releases/download/v0.2.5/$PROXYFIX.tar.gz
tar -xf $PROXYFIX.tar.gz && mv -f $PROXYFIX /usr/local/bin/proxfix && rm -rf $PROXYFIX*

Usage

Use Makefile to build and run the app. Requires make, go and bun already installed.

make build
make run

Envars

Envar Example	Means
NOHUP=1	Run the app detached from this process tree, so when NGINX reloads it will not kill the process. Only works if used for only one instance per linux user.
TARGET=127.0.0.1:1234	Run the app with forwarding HTTP traffic to given IP and port instead of randomly. Useful for apps that can't customize the PORT via envar like Docker

Testing

Use curl and wscat to test with test/app.ts.

curl -H '!~bad-headerz: x' -vvv localhost:8080
wscat -H '!~bad-headerz: x' -c "ws://localhost:8080/ws"
