Go Go Cors Proxy

A simple Go proxy which adds CORS headers to an incoming request. This allows your application to execute requests on a resource hosted on a different domain.

Getting Started

1. Download and install Go
2. Setup your $GOROOT and $GOPATH in your bashrc / zshrc, for example:

    export GOROOT=/usr/local/go
    export GOPATH=/dev/go
    export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

Application Flags

Flag	Default	Description
target	localhost:8080	host:port to proxy requests to
listen	localhost:8181	host:port to listen on
protocol	http	protocol used by the target
host	localhost:3000	host header to be used for the proxy request
origin	http://localhost:3000	origin header to be used for the proxy request
methods	true	enable / disable default access control methods
debug	false	enable / disable debug messages

Running The Application

Once Go has been correctly installed and configured, execute:

go run proxy.go -target=0.0.0.0:8080 -listen=0.0.0.0:8181 -host=localhost:3000 -origin=http://localhost:3000

Now all incoming requests on port 8181 will be proxied to http://0.0.0.0:8080

Here are some basic rules to follow to ensure timely addition of your request:

1. Match coding style (braces, spacing, etc.).
2. If it is a feature, bugfix, or anything please only change the minimum amount of code required to satisfy the change.
3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
