## Starting in namespace

```bash
cd /app/vnfs/cache-squid

ip netns exec netovs0 sh install.sh

ip netns exec netovs0 sh config.sh

ip netns exec netovs0 sh start.sh
```

## Testing 

Try the blocked rule `curl -v --max-time 5 http://www.example.org` the response headers should show some cache information. Some like below or `curl -v --max-time 5 http://detectportal.firefox.com/success.txt` or `curl -v --max-time 5 http://captive.apple.com`

```
< X-Cache: MISS from b345639b6a3e
< X-Cache-Lookup: NONE from b345639b6a3e:3128
```

Check logs to see if the cache was access

```bash
cat /var/log/squid/access.log
```
