Apps will no longer be able to create HTTP proxies

We've started removing all HTTP proxies on the platform. You should transition your app to create HTTPS proxies instead.

The timeline for supporting HTTP proxies is as follows:

• On July 1, 2018, newly created apps will no longer be able to create HTTP proxies.
• On September 1, 2018, all apps will no longer be able to create HTTP proxies.
• On January 1, 2019, all remaining HTTP proxies will be removed.
