How to set favicon?

[Webdev Tory Anderson]

I usually deploy my immutant apps to Wildfly. I'm hoping the solution is the same whether doing wildfly or uberjar: how do I set a favicon for my app? With Wildfly, it's a shared server with multiple standalone deployments (if that matters).

Sorry if the solution isn't at the Immutant level; any pointers on where the favicon specification occurs would be helpful.

I'm no expert, but I don't think there is anything WildFly specific
about this. I believe your pages would just need to include `<link
rel="icon" href="/path/to/icon.ico"/>` on the `head` element. However,
I don't know how various browsers behave with respect to caching, so
if you want to serve different icons from multiple apps on the same
domain from one WildFly, you may see the wrong icon at times.

Ah! I've actually never defined favicons that way; I've just relied on Apache's default behavior of using the favicon.ico from the top-level project directory. I'll try that.
