HTTP Proxy setup (dockerised)

Create a container running squid:
```
docker run --name squid -d -p 3128:3128 sameersbn/squid:3.3.8-14
```

Create a `proxy.pac` file (change IP address as needed):
```
function FindProxyForURL(url, host)
{
    return "PROXY 172.16.10.36:3128" ;
}
```

Create a apache container serving the PAC file:
```
docker run -it --rm --name rneugeba-www -p 8080:80 -v "$PWD":/usr/local/apache2/htdocs/ httpd:2.4
```

The point your proxy config at: `http://172.16.10.36:8080/proxy.pac`
