Hi,
I've started using Microsoft.AspNetCore.SpaServices.Extensions 2.0.0-preview1-final (as described here https://github.com/aspnet/JavaScriptServices/issues/1288#issuecomment-346003334) to enable SSR.

It works just fine. However, during boot of my application I have an XHR request that for various reasons might take some time. If it does, then the SSR will timeout and I get an error like "NodeInvocationException: Prerendering timed out after 30000ms because the boot function in '../Clients/dist-server/main.bundle.js' returned a promise that did not resolve or reject".

Can I set some kind of fallback so that the server ignores requests or aborts SSR if if should take more than a couple of seconds?
