-You may also use a proxy service to load resource that is hosted on domains that aren't CORs enabled. You would first define a variable to hold the proxy service url and set the `proxyService` option for the WFS client. To render a proxy service option for the user, add a user input to the UI. Load the service url when the input is clicked. The following snippets show you how to use the proxy service.
