How does Tomcat handle overlapping/shadowing names in context paths or URLs?

Question

How does Tomcat 8.0 serve http requests in the following scenario?

Let's say we have deployed the two web applications "ROOT.war" and "Foo.war" on a server with the name "www.host.com". Furthermore, let's assume that ROOT.war contains a subfolder named "Foo" which contains a file "mypage.html". Additonally, let's assume "Foo.war" also contains a file named "mypage.html". So after extraction of the war-files Tomcat's webapps directory should look like this:

webapps\ROOT\Foo\mypage.html
webapps\Foo\mypage.html

If a user made a request to

http://www.host.com/Foo/mypage.html

in his browser, which file would he be served? The mypage.html from ROOT.war or the one from Foo.war?

Amplification

Anybody? I'm looking for some kind of reference where Tomcat's behaviour for such a case is specified. – Amplification

Very interesting question which looks trivial if you don't read carefully. – Accusatorial
