Proxy Server

We have been using a Proxy Server called CCProxy out of China. After our iPads updated to iOS8 we started having issues. I have now found out that this Proxy is NOT fully compatible with iPads.

I would like to know what other schools are using for a Proxy. We have made the decision that if we send our devices home, they need to be reconnected to our network and all internet traffic would go through our content filters.

Thanks
