# README for outbound
This project is a small Flask app that merely redirects to the link farther down the URL. The purpose is to enable my web server to record visits to outbound links. This is not a URL shortener or obfuscator. It's a cheap way for me to see what links my site vistors use, without using javascript.
## Upstream
The original project is at .
## Features/design goals
* redirect only if referer is in whitelist
* simple web config
* simple app config
* send to web server logs the redirects, or else 404s for invalid link requests
## Alternatives
Probably some "proper" web analytics suite or javascript garbage that I do not want to learn or use.
## Reason for existence
To show what links on my site are used.
## Using
### Web app
Run a simple dev environment.
FLASK_APP=outbound.py FLASK_DEBUG=True flask run --host=0.0.0.0 --extra-files outbound.conf
### Testing the web app with curl
$ curl --header "Referer: http://d2-03a:5000/" --header 'Debug: true' http://d2-03a:5000/http://server3/

Redirecting...
You should be redirected automatically to target URL: http://server3/. If not click the link.
## Improvements
* Provide an apache wsgi config?
* Provide an nginx wsgi config?
## Dependencies
For the web app:
* apache with `mod_wsgi`
* python3-flask
