niji-proxy

Proxy slitter server. Save data by only proxying the the domains that matter.

Use case

You have a high quality proxy with limited bandwidth. The program using the proxy will try to proxy everything through it (images, scripts, cdn content, etc) but these requests don't actually need to be proxied since almost no CDN is doing any ip filtering. By using this project you can save bandwidth by only proxying the domains that matter (APIs, auth, etc).

Limitations

• Only supports HTTP/HTTPS proxies
• Only filtering by domain (no path filtering, most trafic is encrypted anyway)

Usage

Configuration

Configuration is done through environment variables. (.env file is supported)

Variable	Description	Default	Required
LISTEN_HOST	Host to listen on	0.0.0.0	NO
LISTEN_PORT	Port to listen on	8080	NO
GOOD_HOST_REGEX	Regex to match good hosts	-	YES
GOOD_PROXY	Proxy to use for good hosts (matched by regex)	-	YES
BAD_PROXY	Proxy to use for bad hosts (not matched by regex)	-	NO
DEBUG	Enable debug logging	false	NO

NOTES

Caution

This proxy has not authentication of its own, do not expose it to the internet if you don't want to become an open proxy! It's designed to be used locally (localhost, docker network, etc)

• if GOOD_PROXY has credentials, it will always use them and ignore the credentials from the client
• if GOOD_PROXY has no credentials, it will passthrough the credentials from the client
• if BAD_PROXY has no credentials, no authentication will be used (passthrough not supported to avoid leaking credentials)
• if BAD_PROXY is missing, "bad" connections will be made directly to the target host (no proxy)
• DEBUG will expose credentials in the logs, use with caution

Example

LISTEN_HOST=127.0.0.1
LISTEN_PORT=8080
GOOD_HOST_REGEX=^api\.
GOOD_PROXY=http://user:pass@good-proxy-server:8080
BAD_PROXY=http://bad-proxy-server:8080

Running

git clone https://github.com/dumbasPL/niji-proxy.git

# Create .env file with the configuration

# Using docker
