This is going to be a difficult question, and I really hope someone can help me out here.
I have mentioned before, my son has a Nexus 4 and wants to use Google Now, I have k9 web protection enabled on it, which blocks Google Now, as there is no way to force safe search for google images. However, I have found some interesting information, which I would like to put into practice. According to Google, one can:
2) Update the router configuration
To enable SafeSearch throughout a school network, you can use a proxy server to append &safe=active or &safe=on directly to all search URLs. This will enable strict SafeSearch.
Google Sends search queries along URL paths like google.com/search?..., google.com/images?..., google.com/s?... Schools that activate SafeSearch with a proxy should keep their filters updated to include /search, /s, and /images URLs.
So, I would like to do this. I am not experienced in this, so I was wondering how I would go about this. I just have an AT&T Wi-Fi router. I am guessing I will need my own computer for this, which is a Mac, OS X 10.8.2, on WiFi.
In summary, I need to know how to set up a proxy server on my router, and enable this change of query, on EVERY device. Actually, if that is too difficult, just the phone. Thanks.
