HTTP Proxy

Our SDK uses the standard node http(s) request library, which unfortunately does not automatically pull in environment-defined proxy settings. I think the current options are:

Option 1: Use a Node package for Proxying

Use global-agent to set the proxy settings for the http library so that requests from http use your proxy.

1. npm install --save global-agent
2. Before you use the Optimizely SDK:
