We’re currently following the instructions at https://www.docs.developers.amplitude.com/analytics/domain-proxy/ to set up a Domain Proxy for Amplitude Analytics. We’d like to do the same for Experiment, but have a few questions.

• It looks like Experiment uses https://api.lab.amplitude.com, is that the correct URL to proxy things to?
• It looks like the SDK has `serverUrl` parameters still, are those the right ones to use for the iOS and Android SDKs?
