How to use proxyUrl in 3.4?

[CoreyAlix]

The following code does not affect the proxy.  How is this done in 3.4?

define(["esri/config"], function (esriConfig) { esriConfig.defaults.io.proxyUrl = "foo"; });

I guess I was missing this

esriConfig.defaults.io.alwaysUseProxy = true;

No, you don't have to set alwaysUseProxy as true. It's not recommended unless it's necessary. For example, if the services and the image output folders are behind fire wall or other security settings, and you put the credentials in the proxy. For that case, proxy is always necessary.
